Over the past two evenings, Medeski, Martin and Wood offered four unique sets in support of an endangered New York venue: Tonic. Longtime fans of the avant-garde club, MMW recorded a pair of live albums at Tonic in the late-1990s, Tonic and Electric Tonic. Monday evening, the organ-bass-drums trio expanded to a quintet, welcoming DJ Logic and percussionist Brahim Fribgane. Logic’s appearance was one of several rare spots in the past few days. Friday night, the turntablist turned heads by offering a DJ set at Apt., a trendy lounge located in NYC’s swanky meatpacking district. Fribgane, who likely entered Medeski’s radar through his work with Club d’Elf, also jammed on an oud.

A night later, MMW again welcomed a pair of guests: percussionist G. Calvin Weston and violinist Charlie Burnham. A longtime associate of Billy Martin, Weston most recently joined the drummer, and DJ Logic, at Tonic in December. Burnham, also a longtime MMW collaborator, is best known for his work on the group’s 2000 release, _ The Dropper _. At present, Tonic has raised over half of the $100,000 it needs to survive. The club’s benefit shows continue tonight with a performance by Maroon.
