The great trumpeter and tenor saxophonist were on tour with Benny Goodman's Sextet (which never recorded) in the spring of 1950 and were engaged, singly and together, for three recording dates for Vogue. Joined by Goodman bandmates Dick Hyman and Ed Shaughnessy on one session and Gerald Wiggins and Kenny Clarke on the other two (with Pierre Michelot on all sides), Eldridge and Sims created a prototype for mainstream jazz!
