Outside the UK, the success of Madchester was limited, although some releases gained recognition in specialist charts around the world. In the U.S., the albums "The Stone Roses", "Pills 'n' Thrills and Bellyaches" and "Some Friendly" reached the lower echelons of the U.S. album chart. Several singles by the Stone Roses, the Inspiral Carpets, the Happy Mondays and the Charlatans were successful on the "Billboard" Modern Rock Tracks chart. The Happy Mondays toured the US in 1990 and charted on the "Billboard" Hot 100 with "Step On" reaching No. 57 in 1990. They also reached No. 1 on the Modern Rock Tracks chart, with "Kinky Afro" in 1990. The only other Madchester artist to reach No. 1 on the Modern Rock Tracks chart was the Charlatans, whose single "Weirdo" was No. 1 for the week of 23 May 1992.
