Beefheart would abuse his band members enough to make them cry
The group rehearsed Van Vliet's difficult compositions for eight months, living communally in a small rented house in the Woodland Hills suburb of Los Angeles. Van Vliet implemented his vision by asserting complete artistic and emotional domination of his musicians. At various times one or another of the group members was put "in the barrel", with Van Vliet berating him continually, sometimes for days, until the musician collapsed in tears or in total submission to Van Vliet.[3] According to John French and Bill Harkleroad these sessions often included physical violence. French described the situation as "cultlike"[4] and a visiting friend said "the environment in that house was positively Manson-esque."[5] Their material circumstances also were dire. With no income other than welfare and contributions from relatives, the group survived on a bare subsistence diet. French recounted living on no more than a small cup of soybeans a day for a month[6] and at one point band members were arrested for shoplifting food (with Zappa bailing them out).[7] A visitor described their appearance as "cadaverous" and said that "they all looked in poor health". Band members were restricted from leaving the house and practiced for 14 or more hours a day. Vliet once told drummer John French he had been diagnosed as a paranoid schizophrenic and thus he would see nonexistent conspiracies that explained this behavior.
The album's unconventional nature often alienates new listeners. Cartoonist and writer Matt Groening tells of listening to Trout Mask Replica at the age of 15: "I thought it was the worst thing I'd ever heard. I said to myself, they're not even trying! It was just a sloppy cacophony. Then I listened to it a couple more times, because I couldn't believe Frank Zappa could do this to me – and because a double album cost a lot of money. About the third time, I realised they were doing it on purpose; they meant it to sound exactly this way. About the sixth or seventh time, it clicked in, and I thought it was the greatest album I'd ever heard".
