Vocalist Tony Martin (BLACK SABBATH), bassist Magnus Rosén (HAMMERFALL), guitarist Andy La Rocque (KING DIAMOND) and drummer Danny "Danté" Needham (VENOM, TONY MARTIN) have joined forces in an as-yet-unnamed new "supergroup." The band is currently working on music at La Rocque's Sonic Train Studios in Varberg, Sweden as well as in England. More information will be made available soon.A photo of Martin, Rosén and La Rocque taken in late February in Sweden can be viewed below. Martin took part in two Swedish workshops in Sweden this past weekend — on Friday, February 25 at Gothenburg's Musikstationen (which is owned by Magnus Rosén and Nikolas Gialtrinos) and on Saturday, February 26 at Falköping's Musikskolan. La Rocque and Rosén previously collaborated in the X-WORLD/5 project, which issued its debut album, "New Universal Order", in North America in November 2008 via Locomotive Records. The group also included PAGAN'S MIND vocalist Nils K. Rue. La Rocque and Rosén were also involved with POWERHOUSE, the Swedish supergroup which included Anders Johansson (HAMMERFALL, ex-YNGWIE MALMSTEEN) on drums, Mats Olausson (ex-YNGWIE MALMSTEEN) on keyboards and Mikael Ågren (ex-NOSTRADAMEUS) on vocals and guitar. Martin's last solo album, "Scream", was released in November 2005 via MTM Music. The CD featured legendary drummer Cozy Powell (BLACK SABBATH, RAINBOW, WHITESNAKE) on the track "Raising Hell" as well as songwriting contributions by another SABBATH member, Geoff Nicholls.
