Best known for his film and TV scores (Dirty Harry, Enter The Dragon, Mission Impossible, The Eagle Has Landed, to name just a few) Lalo Schifrin (1932-2025) began as a jazz pianist who worked with some of the most important musicians of his day. The Insensatez session was cut during Schifrin's involvement in Dizzy Gillespie's band, which explains the participation of musicians from that aggregation.
