The funkified jazz trio Medeski, Martin & Wood plays fusion music by way of the downtown New York avant scene of the 1990s. John Medeski's fuzzy keyboards are equally indebted to the Meters, Jimmy Smith, and Sun Ra; and Chris Wood and Billy Martin provide fluid rhythms that can lock in like the JBs if the mood is appropriate. This ability to blend jazz technique and structures with head-nodding grooves endeared the trio to the "jam band" community and its post-Jerry Garcia figurehead, Trey Anastasio of Phish, who joined the band live on several occasions.
