Deep Night (Porto Franco Records)
It may be unfair to say so, but on the surface this gypsy jazz sextet sounds a bit amorphous. On one hand the band doubles as ambience at San Francisco club Amnesia every Wednesday; on the other, listen closely and the music is as nuanced and dexterous as any world-class jazz ensemble. Gaucho’s brilliant playing, it turns out, covers both extremes.
At Amnesia (853 Valencia St., San Francisco) on December 9. 8 p.m., free
