On July 29, 2005, numerous musicians performed at San Francisco's Great American Music Hall to honor the late Chet Helms; the show kicked off the memorial auction, whose proceeds went to the Chet Helms Memorial Fund and Hearing Education and Awareness for Rockers (H.E.A.R.).
Helming the gig was GAMH senior sound tech Lee Brenkman and UltraSound co-founder Howard Danchik. Also on-hand were monitor engineer Will Cotter, Slim's/GAMH staff tech Alex Bendahan and engineer Stacy Parrish. The in-house rig included a 40-channel Soundcraft K2, 32-channel Soundcraft Delta monitor, JBL/UREI graphics, Drawmer gates and dbx compressors; P.A. was a JBL Array Series. Meyer UPM powered monitor wedges were brought “just in case.” Danchik brought in his laptop and SIA Smaart software, as well as a slew of mics. Brenkman says, “The only [mixing] ‘technique’ was Howard's and my years of experience mixing live shows in general and with many of these musicians in particular.”
