German power metallers HELLOWEEN have released a video for the new version of their German Top 10 single "Dr. Stein" with Oliver Sommer from AVA Studios. The clip, which will make its German online debut on January 8 via Tape.tv, is described in a press release as "a comical video where the guys don't take themselves too serious and intentionally present the band in a very self-ironic way!" Check out the video below. HELLOWEEN has teamed up with Sony Music in co-operation with SPV Records, to release the band's upcoming albums. The group's long awaited "Unarmed - Best Of 25th Anniversary" album will be made available in Europe on January 29, 2010. A U.S. release date has yet to be announced.
