The band's music has been officially unavailable since 1992, when they deleted their entire back catalogue. But eight songs, including dance anthems like 3AM Eternal and What Time Is Love, are now available on an eight-track compilation, Solid State Logik. Fly posters in London suggested The KLF would release more music this year.
