BRITISH Christian music's most significant music movement since the 60s - the rapid growth in popularity of acoustic-based folk-tinged music - continues to gather momentum. Kingsway's Acoustic Revolution label is launched in February with the release of the debut album by Nuffsed. The Midlands-based team will be introducing their album "Fields Keep Calling' by undertaking a year long Cover To Cover tour with in-store appearances in Christian book shops as far away as Birmingham, London and Plymouth. Said Nuffsed lead singer Terry Mills, "We will be playing free mini-concerts, usually on Saturday lunchtimes. The Cover To Cover tour will spread out over a 12-month period as we have to fit our appearances around existing concert, mission and festival gigs."
