Having moved from jazz, Blues and R'n'B to out-and-out pop in his various 1960s bands, keyboard player Manfred Mann went back to the drawing board in 1971 with a new quartet, Manfred Mann's Earth Band, and the intention of focusing on progressive rock. With a repertoire that leant partly on radical rearrangements of songs by Bob Dylan and then Bruce Springsteen, largely instrumental epics that borrowed from Gustav Holst's The Planets suite, and improvisations based around the interplay between Manfred's newly-acquired moog synthesiser and the lead guitar of Mick Rogers, who left in 1975 but later returned, they soon built up a formidable live reputation throughout much of Europe (particularly in Germany) and America. Apart from the Holst-inspired 'Joybringer', a top ten hit in 1973, British success was slow in coming, until a cover version of Springsteen's 'Blinded by the Light' and its parent album The Roaring Silence three years later took their status to a new level on both sides of the Atlantic. This book examines the nine albums, fluctuating fortunes and various line-up changes from what was to be their best and most prolific decade.
