text_A: In 1952 Mingus co-founded Debut Records with Max Roach so he could conduct his recording career as he saw fit. The name originated from his desire to document unrecorded young musicians. Despite this, the best-known recording the company issued was of the most prominent figures in bebop. On May 15, 1953, Mingus joined Dizzy Gillespie, Parker, Bud Powell, and Roach for a concert at Massey Hall in Toronto, which is the last recorded documentation of Gillespie and Parker playing together. Mingus chose afterwards to overdub his bass part in New York, which was previously hard to hear, and the original version was released later. The two 10" albums of the Massey Hall concert (one featured the trio of Powell, Mingus and Roach) were among Debut Records' earliest releases. Mingus may have objected to the way the major record companies treated musicians, but Gillespie once commented that he did not receive any royalties "for years and years" for his Massey Hall appearance. The records, however, are often regarded as among the finest live jazz recordings.
text_B: From this passage, does it sound like Mingus himself was satisfied (or at least, mostly satisfied) with how his bass performance turned out in the original recording?
NO.
