at Lawrence University), Larry Darling (sound) and Jillian Johnson (administration) DLB dedicated the October 29, 2011 performance at Lawrence University in Appleton, WI to the memory of David Gamper. As a tribute to Gamper DLB released three albums featuring the long time trio Dempster, Gamper and Oliveros: Octagonal Polyphony (Important Records, vinyl), Great Howl at Town Hall (Important Records, CD) and Needle Drop Jungle (Taiga Records, vinyl). The band celebrated its 25th anniversary with a weeklong residency culminating in a concert at the Dunrobin Sonic Gym in Ontario, Canada in October 2013. On this occasion the band employed the Cistern Simulation Technology, a simulation of the Fort Worden Cistern acoustics, developed by Jonas Braasch, Director of the Center for Cognition, Communication, and Culture at Rensselaer Polytechnic Institute. Both residency and concert featured founding members Pauline Oliveros and Stuart Dempster as well as special guests Jonas Braasch (saxophone), Jesse Stewart (percussion, sonic artifacts) and Johannes Welsch (gongs). The concert, which opened with an invocation by IONE (author, playwright, director), was recorded by Braasch and Welsch, and released by Deep Listening as Dunrobin Sonic Gems on October 8, 2014, marking the 26th anniversary of the seminal Fort Worden Cistern recording. On this occasion DLB also released "Johina", an excerpt from the soundcheck preceding the concert, as a standalone composition for download.
