I have a test where I am given the following article, what is an answer for the question: What are the specific names of the two albums that were musically akin to Hot Rats? ?

On December 4, 1971, Zappa suffered his first of two serious setbacks. While performing at Casino de Montreux in Switzerland, the Mothers' equipment was destroyed when a flare set off by an audience member started a fire that burned down the casino. Immortalized in Deep Purple's song "Smoke on the Water", the event and immediate aftermath can be heard on the bootleg album Swiss Cheese/Fire, released legally as part of Zappa's Beat the Boots II compilation. After losing $50,000 (equivalent to $309,000 in 2018) worth of equipment and a week's break, the Mothers played at the Rainbow Theatre, London, with rented gear. During the encore, an audience member jealous because of his girlfriend's infatuation with Zappa pushed him off the stage and into the concrete-floored orchestra pit. The band thought Zappa had been killed—he had suffered serious fractures, head trauma and injuries to his back, leg, and neck, as well as a crushed larynx, which ultimately caused his voice to drop a third after healing.This attack resulted in an extended period of wheelchair confinement, making touring impossible for over half a year. Upon return to the stage in September 1972, Zappa was still wearing a leg brace, had a noticeable limp and could not stand for very long while on stage. Zappa noted that one leg healed "shorter than the other" (a reference later found in the lyrics of songs "Zomby Woof" and "Dancin' Fool"), resulting in chronic back pain. Meanwhile, the Mothers were left in limbo and eventually formed the core of Flo and Eddie's band as they set out on their own.
During 1971–72 Zappa released two strongly jazz-oriented solo LPs, Waka/Jawaka and The Grand Wazoo, which were recorded during the forced layoff from concert touring, using floating line-ups of session players and Mothers alumni. Musically, the albums were akin to Hot Rats, in that they featured extended instrumental tracks with extended soloing. Zappa began touring again in late 1972. His first effort was a series of concerts in September 1972 with a 20-piece...
