The band’s first single of 1981, “This Is Radio Clash” displayed The Clash’s ability to seamlessly weave their hip-hop and dub influences into a single sound that still maintained its own originality. Though it never appeared on any of their studio albums, its release provided a second track entitled “Radio Clash,” which was a remix of its predecessor. They would perform “This Is Radio Clash” for the first time on a June 5th, 1981 episode of The Tomorrow Show, months before its November 20th release date.

Years following the track’s release date, a reviewer would say:

[“This Is Radio Clash”] is a magnificent, daring, challenging record that was years ahead of its time; one of the great rock records of the 1980s, it has never been given its just credit. Twenty-eight years after its debut, were it released today it would still burn up the radio.
