UMRK

Frank Zappa’s home recording studio “Utility Muffin Research Kitchen”. (Also referred to as "UMRK, Hollywood" or "UMRK Central"). This facility is strongly featured in FZs work, not only for recording but for remixes, overdubbing, etc.
For the remote facility use: UMRK Mobile

The acronym "UMRK" features in Zappa's mobile/remote recording facility title "UMRK Mobile" (Originally the remote facility of The Beach Boys). Zappa's last recording outside of UMRK was Mark Pinske was the first engineer employed by FZ to sit at the UMRK console.

Much of UMRK was rebuilt in 1980 by engineer Johnny Guitar Watson, an event that was featured in a BBC TV documentary.
