Vibraphonist Gary Burton and bassist Steve Swallow had played together on a regular basis since 1967. This duet outing finds Burton switching between vibes, organ and marimba while Swallow doubles on occasional piano. As expected, the music is introverted, quiet, and occasionally swinging, but mostly floating. Burton and Swallow perform group originals (generally by Swallow), plus Carla Bley's "Vashkar" and Mike Gibbs' "Inside In." Thoughtful background music with no real surprises or excitement.
