Deep Purple and Rainbow bassist Roger Glover always remained tirelessly busy on extracurricular projects. Joining Deep Purple in 1969, following previous acts The Madisons and Episode Six, alongside Ian Gillan the bassist began work outside of the Deep Purple framework as early as 1972 that included production for such acts as Nazareth, Judas Priest, David Coverdale, Elf, and Rory Gallagher.
Finding the internal pressures within Deep Purple too much to cope with Glover quit the band in 1973 opting to take the A & R position at Purple Records and concentrate on production. During 1974 Glover set aside time for a substantial solo project, The Butterfly Ball, a concept album based upon the children’s poems of William Plomer.
It was intended to be a further solo vehicle for Deep Purple keyboard player Jon Lord initially, but with the noted Hammond player busy on the road it was Glover who took the mantle. Musicians enrolled included Spencer Davis Group’s Eddie Hardin and Fancy musicians guitarist Ray Fenwick, bassist Mo Foster and drummer Les Binks.
A whole host of vocalists made appearances on the album in order to give each song and character a unique distinction. Noted names included then Elf vocalist Ronnie James Dio (later of Rainbow, Black Sabbath and Dio), Deep Purple singers David Coverdale and Glenn Hughes, keyboard player Tony Ashton, Quartermass and Episode Six bassist John Gustafson, Uriah Heep’s John Lawton and Neil Lancaster. The album also included a performance by Judy Kuhl, who was later to marry Glover.
A single pulled from the record, Love Is All, reached Number One in Holland, France and Belgium. Only one live show was arranged to promote the album, that being at the Royal Albert Hall on October 16th 1975.
In addition to the Butterfly Ball project, Glover also made major contributions to Eddie Hardin’s concept album. The Wizard’s Convention released in December 1976 before another solo effort, Elements, based on a Glover poem, was released in 1978.
Based loosely on the four earth elements, and originally to be titled The Eyes of Omega, the album was more in line with atmospheric film score music than Rock although Elements featured contributions from Deep Purple’s David Coverdale and Elf keyboard player Mickey Lee Soule.
1978 also found Glover producing and performing on the debut album from Playboy magazine model Barbie Benton “Ain’t That Just The Way”. Both Glover and Coverdale contributed on the songwriting front, too.
Following this project Glover finally succumbed to the overtures being made to him by his former Deep Purple colleague guitarist Ritchie Blackmore by joining Rainbow in time to record and produce the successful Down To Earth.
In 1983 Glover found time to record the Mask solo album featuring vocalist Kate McGarrigle, guitarist Craig Brooks of Touch, ex-Paladin and Midnight Flyer guitarist Joe Jammer, veteran keyboard player Don Airey, guitarist Jean Roussell and Rainbow colleagues drummer Chuck Burgi and keyboardist David Rosenthal. After this outing he became involved in the rebirth of the classic Deep Purple Mark II line-up during 1984.
Deep Purple’s 2000 European tour opened up with passages from Glover's Butterfly Ball including contributions from Ronnie James Dio and Miller Anderson. The bassist issued a new studio album entitled Snapshot in September of 2002, the fruition of several years work.
