To prepare for this fully solo guitar album, Bill Frisell spent a week playing solo at the famed New York venue The Stone, trying to play new material every night and to keep himself from getting musically comfortable. Then he went into the studio, and what came out of the resulting sessions is one of the most beautiful and crystalline albums of his long and storied career. Some of the tracks are older material (“Rambler,” “In Line”), but all of it shimmers with new ideas and new intonations.
