It was an event when this star-studded group reconvened after more than 25 years to release RoundAgain, the (very) belated follow-up to Joshua Redman’s MoodSwing from 1994. Rather than scatter to the winds, the quartet stayed intact to document a set of five Redman originals on LongGone. “Rejoice,” originally from MoodSwing, is heard at the end in an exploratory live take from the San Francisco Jazz Festival. Redman shows depth and range as a writer with the moody and chamberlike “Statuesque,” the lilting, lyrical swing of “Long Gone” and “Ship to Shore,” and the jaunty modernism of “Disco Ears” and “Kite Song.” Mehldau and Redman have a fiery, richly complementary blend as the prominent soloists, a quality they also documented on the 2016 duo release Nearness.
