Kember recruited new musicians Richard Formby, who had previously contributed guitar and keyboards to Sonic Boom's side of the final Spacemen 3 album 'Recurring', and Mike Stout for the group Spectrum in 1991. Initial Spectrum releases carried on from the sound of late-period Spacemen 3, featuring conventional songs and a regular band. First single "How You Satisfy Me" was an original composition by Kember and Formby reminiscent of 1960s garage bands, based as it was upon the Chip Taylor-penned pop hit "Can't Let Go". 1992's "Soul Kiss (Glide Divine)" album was split between songs and longer experimental pieces featuring drones and repetition. Another single from the album, a cover version of Daniel Johnston's "True Love Will Find You in the End" reached number 70 on the UK singles charts. Formby departed the band as soon as the album was released and Stout left not long after. 'Highs, Lows and Heavenly Blows' (1994) featured a new line-up including former Spacemen 3 bass player Pete Bassman (Pete Bain), was also mainly song-oriented. Kember has occasionally collaborated with Jessamine and The Silver Apples under the Spectrum name.
