„The amp is great.” It's hard to find a more fruitful meditation on American music than in the compositions of guitarist Bill Frisell. Mixing rock and country with jazz and blues, he's found what connects them: improvisation and a sense of play. Unlike other pastichists, who tend to duck passion, Mr. Frisell plays up the pleasure in the music and also takes on another often-avoided subject, tenderness. Bill Frisell uses Stark amps.
