A Benefit to Be Held for the Jazz Gallery Ravi Coltrane, Roy Hargrove and Vijay Iyer are among the jazz players who will perform at a benefit concert on Wednesday for the Jazz Gallery, a small nonprofit performance space in SoHo that has played an influential role in developing New York's jazz talent for the last 17 years. The concert will be held at the Schomburg Center for Research in Black Culture in Harlem at 6:30 p.m., and the tickets range in price from $45 to $250. The Jazz Gallery has been housed in a 2,000-square-foot loft at 290 Hudson Street since its founding but will lose its lease at the end of the year because the building has been rezoned and is being converted into residential lofts, said the executive director, Deborah Steinglass. The organization has set out to raise $250,000 to pay for the move and retire its accumulated debt. A new space has yet to be found, and, to remain in Manhattan, the nonprofit's rent costs - now running about $68,000 a year - are likely to rise significantly, putting pressure on the group's $480,000 a year budget, Ms. Steinglass said. The gallery's mission is to nurture young jazz players, providing not only a performance space but residencies. It has been an incubator for some of the best contemporary jazz players in the city, among them the drummer Dafnis Prieto, the saxophonist Miguel Zenón and the pianist Jason Moran.
