Bill Frisell has been a regular guest of the New York Guitar Festival, and as with all of his past appearances, he is bringing a new duo partner. This time, it’s the Icelandic composer and bass guitarist Skúli Sverrisson, whose discography includes work with Laurie Anderson, Lou Reed, Wadada Leo Smith, and over a hundred others. Frisell, meanwhile, has a discography best described as epic. It includes work with Elvis Costello, jazz legend Elvin Jones, and British composer Gavin Bryars. He has routinely ignored genre categories, working across rock, jazz, country, experimental, classical, and West African music. Guitar fans can be a contentious, opinionated lot – but there is unanimous agreement on Frisell’s place in the pantheon.
