Jim Hall & Bill Frisell, Hemispheres (ArtistShare). Hall inspired Frisell. The younger guitarist famously became what Hall would have encouraged him to be, his own man. On Dialogues in 1995, they showed flashes of what they could develop together. On this 2-CD set, they follow through, in duo and with bassist Scott Colley and drummer Joey Baron. Everything works, from Frisell’s outré “Throughout” at the beginning to Sonny Rollins’ blues “Sonnymoon for Two” at the end.
