Pouliční Galerie s Interferencí (2026) Video and Sound by Dan Senn


2026 Duration 5:40	4K/2K Video & Found Objects + Flute & Bass Drum(s) by Dan Senn (see video demo) Use head phones!
Pouliční Galerie s Interferencí ('26) (PGsI), further develops Uličnická Galerie ('25) (UG) by adding flute and drum parts. Both Czech titles translate, in part, to "Street Gallery" with the new work, PGsI, emphasizing patron interferences in the video. Therefore, PGsI is for found video & sound objects + flute & bass drum(s). The Introduction of a text describing the making of these works follows. Pouliční Galerie s Interferencí (PGsI) is an iterative, experimental work developed from Uličnická Galerie (UG) made from two found-object improvisations, one audio and the other video. This text details the compliant merger of standalone artifacts, preserving their integral spontaneity, and provides a non-destructive strategy for the inclusion of live traditional instruments to produce a new work, PGsI. It also touches on the advantages of nonlinear, found instruments in repressing “mirroring” in free improvisation." Read the full text. Journal Recap... Related text -> "RKM Interviews Dan Senn" For PGsI, two videos must be synchronized and presented on different output screens: 1) A conducted score for the instrumentalists viewed on the computer monitor. Here is the score video with conducting line and 2) A 2K projected video (with stereo sound) beamed on a 16:9 screen at the front of the performance space. This file is at 2K or 4K depending on your projector or computer speed. The score video + the projected video, again, must be played in synch from the computer (middle column). Here is a PDF of the full score (not used during performance). Score Video Alternatives for Rehearsal: The score video is read from the computer screen by the flutist and mirrored (if necessary) on an iPad for the percussionist(s), is in 2K or 720 format. The score videos are in the variations listed below. The 720 versions are smaller and easily streamed for rehearsal. 720-Score or 2K vs. 720-Score+FixedSnd or 2K vs. 720-Score+FixedSnd+DrumSnds+Insert or 2K vs. 2k-Score+FixedSnd+FluteSnd+DrumSnd+Insert. 720-Score+FixedSnd+Insert or 2K vs. 720-Score+FluteSnd+DrumSnd or 2K vs. 720-Score+ClickSnd The Performance Gear (see graphic) includes a 16:9 projection screen (back projection is best), a bright 2k or 4K projector, a fast computer holding two projection files like a 2K version of the projection video and a 720 version of the score video, a HDMI cable connecting the computer to the projector, two large self-amplifed speakers with 15" woofers, a balanced cable between the computer interface (like an Focusrite) and speakers and, if necessary, 1 or 2 iPads to mirror the computer screen. The flutist and optional live percussionist(s)* should begin by inspecting the score pdf and then the conducted score video options listed above.	Performance Setup Click to enlarge setup. The screen is centered between (or above) the live players who are positioned not to obstruct the projected images. The score video may need to be mirrored on an iPad from the computer for the percussionist(s). A technician may be needed to work out the logistics, use of a Windows computer, synchronization, setting balances, etc. Hardware setup: Attach a video projector (beamer) to the HTML port of the computer after setting the computer's System Preferences, Displays to the highest resolution. Balance and Sound Quality: The stereo sounds from the projected video should be loud and yet the flute must always be heard and, therefore, may need to be area miked/amplified over a small speaker. Synchronization software is needed for PGsI to play two video files simultaneously—specifically a score video and a projected video with its stereo sound tracks. The easiest software for this synchronization is QuickTime on a Mac (see QuickTime Instructions) but VLC also works. The least amount of computer overhead is used here when synching a 2k Projected Video with a 720 Score Video with WiFi and Bluetooth shut off. The most is used when synching a 4K Projected Video with a 2K Score Video with WiFi and Bluetooth on. If the PGsI is played without live drums use either the 2K Projected Video with Pre-Recorded Drums or the 4K Projected Video with Pre-Recorded Drums. The live instrumentalists should rehearse primarily with the 720 Score Videos as these are faster loading and tablet freindly. For the performance, either a 720 or a 2k Score Video is played over the computer screen, read by the flutist with its content mirrored (if necessary) on an iPad(s) for the percussionist(s). Preparing the Two Performance Files for Synchronization: Choose a 2K or 4K Projection File with or without pre-recorded drums and then a 720 or 2K Score File placing them in a desktop folder on the computer for quick access.	QuickTime Instructions: With the projector attached to the main computer drop the chosen score video file* and then the projected video file onto the QuickTime app. Once open, pull the Projected Video file to the projector and resize it to fill the entire screen. Then pull the score video file onto the computer screen and resize it to fill the entire screen. Set each video to start from the beginning. Simultaneously press the Command and Return keys to start or pause the videos. The two files will synch perfectly. Videos stop on their own at the end. Download all performance video to computer for performance. Do not stream them. Redundant Performance Instructions:::PGsI requires a large 16:9 screen, a 2K or 4K video projector, a substantial stereo sound system, a flutist and possible percussionist(s). The stereo speakers should have a 12-15" woofer. The performers include a flutist and an optional percussionist(s) playing bass drum (soft mallets) on its side. If a second percussionist is used, add a street bass drum (harder mallets). The flutist and drummer(s) play from the same composite score video viewed on the host computer, mirrored, if necessary, using iPad(s)s for the drummer(s). The videos are synchonized with the projected video using QuickTime. PGsI may be played using a solo flutist alone with the percussion parts pre-recorded and as part of the projected audio tracks. Furthermore, a single drummer may be used to play all the percussion parts on one drum. If a second drummer is desired, a street (parade) bass drum should be used (see Score PDF) also placed on its side. If PGsI is played without live drums use 2K Projected Video with Pre-Recorded Drums or the 4K Projected Video with Pre-Recorded Drums. Dan Senn (Prague-Watertown) is an intermedia artist working in music composition and production, kinetic sound sculpture, and experimental/documentary film. He has been a professor of music and art in the United States and Australia and travels internationally as a lecturer, producer, performer and installation artist. His doctorate is in Music Composition and Ceramics from the University of Illinois-Urbana. He lives in Prague where he directs the Echofluxx media festivals, and Watertown, Wisconsin, the USA. Dan's work moves freely between expressive extremes and languages depending upon the aesthetic joust at hand. He is cofounder of Roulette Intermedium in New York City, Cascadia Composers of Portland Oregon, and the Echofluxx media festivals in Prague.
