Tonally, the euphonium is similar to a trombone, which Ball handles in several Denver-area groups. No wonder his playing on the likes of "Peter Rabbit" feels so warm and familiar. The performances -- by Ball, pianist Vlad Girschevich, bassist Eric Thorin and drummer Ben Makinen -- aren't particularly adventurous; they generally settle for post-bop safety. Nevertheless, offerings such as "Bluz 4 T Man," boosted by a trickier-than-usual arrangement, exude an effortless charm.
Elementary schoolers may not clamor for euphoniums because of Ball's undertaking. Still, Fishleather Jacket wears well.
