September 6. Jazz nuts generally know saxophonist Dave Liebman from his years with Miles Davis's early '70s fusion band or via the other legends he's worked with, like Chick Corea, McCoy Tyner, John McLaughlin, and Elvin Jones. No mere sideman, Liebman has over the years also led his own amazing bands, such as the trio Open Sky and his current Expansions quintet, which makes magic at the Falcon this month. "Conceptually," the band's bio reads, "the repertoire traverses elements of free jazz and rearrangements of standards, all infused with complex time signatures and harmonies." (Dave Stryker strikes September 14; Kenny Werner keys in September 22.) 7pm. Donation. Marlboro. (845) 236-7970; Liveatthefalcon.com.
