Weinstock was known for having artists record with almost no rehearsal time, recording large quantities of music from the jazz groups in New York City for Prestige and later its Bluesville, Moodsville, Par, Swingville and Tru-Sound imprints. He would have musicians record on one take, insisting that the additional takes were less spontaneous and that recording engineer Rudy Van Gelder did not need extra takes to adjust balance, and would reuse tapes if he thought that another take was needed. This left very few alternative versions of Prestige recordings. John Lewis and his Modern Jazz Quartet were one of the few able to overcome Weinstock's no-rehearsal practice, for the 1955 release of "Concorde" and for the 1956 album "Django". Sonny Rollins and John Coltrane recorded the album "Tenor Madness" in 1956, with a saxophone duet that marked the only known recording of the two artists together.
