Marvin Stamm, Alone Together (Jazzed Media). Trumpeter Stamm’s quartet with pianist Bill Mays, bassist Rufus Reid and drummer Ed Soph reaches its peak in this concert at Rising Stars, a cozy Southern California concert space. Equipped with microphones, cameras and lighting, the little hall is also a state-of-the-art audio and video studio. We see and hear the musicians with clarity, intimacy and a variety of camera angles rare in jazz DVDs. From the chance-taking opening of the title tune to the rip-roaring “T’s Butter,” this hour-and-twenty-minute concert is a joy. The DVD comes with a bonus CD of the performance, minus a few minutes of spoken material.
