The Utility Muffin Research Kitchen (UMRK) is a recording studio built in 1979 by musician, composer, songwriter, and bandleader Frank Zappa at his home in Los Angeles, California.
[1] Soon after the studio was completed, Ken Scott engineered the four song debut EP by Missing Persons at UMRK.
In 2016, Lady Gaga purchased the Zappa homestead,[3] including the Utility Muffin Research Kitchen.
The UMRK Mobile Studio was a remote recording bus purchased from Mike Love of the Beach Boys.
The studio bus needed extensive repairs and upgrades after years of sitting idle at Love's home.
