The latest ECM album to feature pianist Ethan Iverson – following last year’s duo recording with saxophonist Mark Turner, Temporary Kings, and two lauded discs with the Billy Hart Quartet – presents the Brooklyn-based artist at the head of his own quartet in a program of standards and blues, recorded live at Manhattan’s famed Village Vanguard. Iverson’s quartet for "Common Practice" features as its prime melodic voice the veteran Tom Harrell, who was voted Trumpeter of the Year in 2018 by the U.S. Jazz Journalists Association. Iverson extols the quality of poetic “vulnerability” in Harrell’s playing, particularly in such ballads as “The Man I Love” and “Polka Dots and Moonbeams,” two of the album’s highlights. "Common Practice" also courses with an effervescent swing, thanks to the top-flight rhythm team of bassist Ben Street and drummer Eric McPherson, whose subtle invention helps drive Denzil Best’s bebop groover “Wee” and two irresistibly bluesy Iverson originals.
