Just look at this partial list of musicians who have valued George Coleman’s saxophone playing enough to call on him for help: Miles Davis, Chet Baker, Charles Mingus, B.B. King, Lee Morgan, Ahmad Jamal, Max Roach, Cedar Walton, Elvin Jones, Herbie Hancock, Ray Charles, Horace Silver. It goes on, but you get the picture. More important though, at 84, Coleman, named an NEA Jazz Master in 2015, is still active, and still creative. He’s favored the quartet format since he first started making recordings as a leader in the late ‘70s, and for his newest set, he’s reconvened one of his go-to assemblages: pianist Harold Mabern, whose relationship with Coleman has roots in their high school days (they first recorded together in 1968), along with bassist John Webber and drummer Joe Farnsworth, both of whom also go back a couple of decades. It’s no wonder Coleman has dubbed this recording so definitively as The Quartet : These are his guys, and from the first note, they come out swinging. “Paul’s Call,” a Coleman original, allows both the saxophonist and fellow octogenarian Mabern to make it clear that age doesn’t have any impact on their abilities. There’s only one other Coleman original, the 12-minute “East 9th Street Blues,” and it’s a beaut, showcasing all four musicians amply and giving Coleman all the solo space he needs to take it to the limit. Among the covers is the album’s finale, Jobim’s “Triste,” which gives the quartet its best opportunity to move into a new space; in this case, it’s the more rarefied air of Brazilian rhythm, all cool and sharp and full of swagger.
