TIM BERNE AND LOS TOTOPOS (Saturday) Mr. Berne, an alto saxophonist and composer with a taste for coarsely layered frictions, presents a newly minted ensemble here, with Matt Mitchell on piano and electronics, Oscar Noriega on clarinets and Ches Smith on percussion. The band focuses not only on sharp and convoluted new music by Mr. Berne, but also on some rather obscure material written more than 30 years ago by his former mentor, the saxophonist-composer Julius Hemphill. At 8:30 p.m., Roulette, 20 Greene Street, at Grand Street, SoHo , (212) 219-8242, roulette.org; $15; $10 for students. (Chinen)20091119
ELLERY ESKELIN QUARTET (Sunday) Ellery Eskelin is a tenor saxophonist drawn to rhythmic tumult and tonal discord, though he also has his soulful side.

At 9 and 10:30 p.m., Cornelia Street Café, 29 Cornelia Street, West Village , (212) 989-9319, corneliastreetcafe.com; cover, $10, with a $6 minimum. (Chinen)20091119
