Slade was an original founding member of Manfred Mann's Earth Band, playing on their eight studio albums released from 1972 to 1978.

The Young brothers (Angus and Malcolm) initially hired Slade only temporarily through management, then asked him–during the recording of the only album he made with them – to join the band.

Slade played on The Razors Edge album in 1990 and the accompanying world tour, and the "Big Gun" single released in 1993.

[6] After his departure Slade spent a few years living in the UK countryside, before receiving a call from Geoff Downes of the British progressive rock group Asia.

The band takes music from all aspects of his lengthy career and has appeared at major festivals including Hellfest, 24 Hours of Le Mans, Harley Davidson Aquitaine, and Saint Tropez and is the only rock band to play the Moscow Olympic Stadium for the Kremlin Cup tennis tournament.
