Medeski Martin & Wood and John Scofield have collaborated on two albums to date, Scofield's A Go Go and the more recent Out Louder. You can find them with several names, here at Last.fm: Medeski Scofield Martin and Wood and Billy Martin, Chris Wood, John Medeski & John Scofield are some variations possible.
The band received some of their first significant exposure outside of the New York City jazz scene by performing with Phish at their October 14, 1995 concert, which led to the association of the group as a jam band.
In addition, their performance on John Scofield's 1997 album A Go Go helped to further their exposure. The band collaborated further with Scofield again in 2006, releasing the album Out Louder under the name Medeski Scofield Martin & Wood. This was the first album released on MMW's own Indirecto Records.
Medeski Martin & Wood's first performances together were at the Village Gate, a popular New York jazz club. They were initially an acoustic jazz trio, but Medeski added a Hammond organ when the difficulties of touring with a piano became apparent.
Their first album, Notes from the Underground, is a record of their entirely-acoustic era. All of their subsequent albums reveal Medeski's use of a wide variety of keyboards, including mellotron, melodica, and a clavinet. Wood entirely eschewed the electric bass for MMW's first three albums, and still relies heavily on the acoustic upright bass in recordings and during live performances. Their earlier albums reveal a Hip Hop influenced updating of classic soul jazz sounds, which is the primary theme of their well-known 1996 album, Shack-man.
From 1998 to 2005, MMW were signed to leading jazz label Blue Note Records, and showed them delving deeper into dense, electronic funk than their earlier albums, although the band continued to experiment with free jazz and free improvisation both on their albums and in concert. In 2001 MMW performed several songs for the Red Hot Organization's compilation album Red Hot - Indigo, a tribute to Duke Ellington, which raised money for various charities devoted to increasing AIDS awareness and fighting the disease.
Medeski Martin & Wood's live performances are renowned for their exploratory nature. Their concerts usually involve extended improvisations, which may be both arrhythmic and atonal, an aspect of their musicianship that is rarely documented in the studio. They occasionally tour using only acoustic instruments, reverting to the instrumentation that they began their career with. Their album Tonic is an example of these more contemporary acoustic performances. They have also done short tours of entirely improvisatory performances. These shows usually consisted of two sets of improvisation, followed by an encore of a song from an album.
