Waka/Jawaka (intended by Zappa as a sequel to Hot Rats) was recorded in 1972, while Zappa was recuperating from being pushed off stage at the Rainbow Theatre in London by a crazed attendee. Although he was confined to a wheelchair and in immense pain, his work ethic could not be tamed, and he would end up having one of the most prolific years of his hugely prolific career. During this time, he managed to record two albums - Waka/Jawaka and The Grand Wazoo. Waka/Jawaka was recorded with a pared down version (of six to nine musicians) of the 20-piece ensemble he had assembled for The Grand Wazoo. Mastered from the analog tapes by Bernie Grundman.
