In the 12 years since Frontiers Records pulled them together, melodic hard rock supergroup W.E.T. – the one-time trio comprising Work Of Art keyboard player Robert Säll (whose group provide the name’s ‘W’), guitarist Erik Mårtensson from Eclipse (‘E’) and frontman Jeff Scott Soto of Talisman (‘T’) – have made four albums and evolved into a six-piece. With a new album, Retransmission, out, we caught up with Mårtensson.
