On recent programs we’ve heard several cuts - on this show it’s “Hangover” - from guitarist John Scofield’s new quartet CD, Past Present. Scofield has gathered together the early 90s lineup he led with saxophonist Joe Lovano and drummer Bill Stewart, and added bassist Larry Grenadier. Scofield recently lost a son to cancer and the experience focused his sense of how vividly the past survives in the present. Thus the title of the new work. The recording displays his predilection for the blues, country music and soul-jazz he loved in his own youth.
