Bill Frisell There seems to be a perception in modern jazz that free playing must be harsh and grating or at least difficult to absorb on first listen. “Hemispheres,” a jazz guitar summit between 50-year veteran Jim Hall and Americana-dusted experimentalist Bill Frisell dispels that notion. On the 15-minute spacescape “Migration,” Frisell’s effects-pedal orchestra forms a hypnotic backdrop. Here Frisell plays with his trio. Largo at the Coronet, 366 N. La Cienega Blvd., L.A.. 7:30 and 10 p.m. $25-$40. (310) 855-0350.
