For its fifth album as a unit, The WeeTrio, James Westfall (vibes), Dan Loomis (bass) and Jared Schonig (drums) has chosen to double down. Literally. The group has expanded twofold for this outing, recruiting colleagues Nicholas Payton (trumpet), Nir Felder (guitar) and Fabian Almazan (piano) to appear as guest soloists on individual tracks. The result is a spirited, intellectually rigorous 11-piece program that respects the diversity of the individuals involved while pointing to a shared aesthetic of lush grooves and winsome improvising.
