Even if you have had the pleasure of hearing classic Kurt Weill compositions like “September Song,” “My Ship,” and “Alabama Song” hundreds of times, you’ll still find much to marvel at on Tethered Moon: Masumi Kikuchi, Gary Peacock, and Paul Motian Play Kurt Weill. This revelatory collection finds pianist Kikuchi, bassist Peacock, and drummer Motian making innumerable harmonic and melodic discoveries. This is especially true of the leader’s work, which often veers off in bluesy directions (as on “Alabama Song”) or pauses to revel in somber aural shadows. Kikuchi’s unaccompanied reading of “It Never Was You” is a wonderful evocation of wistful recollection. The meditative “My Ship” is only slightly undercut by a Charlie Haden sound-alike solo from Peacock, whose own equally arresting instrumental voice is more than up to the task posed by Weill’s haunting compositions.
