several local scenes had grown up in the US. The Detroit rock scene included: The Von Bondies, Electric Six, The Dirtbombs and The Detroit Cobras and that of New York: Radio 4, Yeah Yeah Yeahs and The Rapture. The commercial breakthrough from these scenes was led by bands including The Strokes, who emerged from the New York club scene with their début album Is This It (2001) and The White Stripes, from Detroit, with their third album White Blood Cells (2001).
