This small book is from series "33 1/3". It's about album Trout Mask Replica, written as a personal passion, but contains a lot of additional information on Captain Beefheart, The Magic Band and Frank Zappa.

 On Easter Sunday 1969, Zappa called up Vliet and told him that the album was done. Beefheart had all the guys in the band get dressed up, "as if they were going to Easter church," Zappa recalled. They came over to Zappa's studio early that morning and sat in his living room and listened to it. Apparently, they loved it.
