With a chemistry forged over 15 years of playing together in many different musical configurations, the Chicago-based trio of bassist Clark Sommers, saxophonist Geof Bradfield and drummer Dana Hall have developed a trust and intuitiveness that yields high levels of creative spontaneity. Drawing from their many diverse influences, Ba (SH) is alternately raw and elegant, while always riveting, as they explore a set of eight modern jazz originals plus readings of Billy Higgins' "Inga," and Monk's "Think of One. " Peripatetic bassist Clark Sommers plays with a rock-bottom, infectious groove; communicates his personality through his playing, and is securely steeped in the jazz tradition."
