Twin brothers, Jasun and Troy Tipton along with Erik Rosvold released two albums with the Progressive-Metal act Zero Hour. Michael Rensen of the premier German magazine Rock Hard proclaimed, "Zero Hour is one of the five Best Progressive Newcomers in the late '90s!" The band's second album "The Towers of Avarice" (Released by The Laser's Edge/Sensory label) won sparkling reviews from nearly every magazine around the World. Such magazines included Hit Parader, Metal Maniacs, Bass Player and Sci Fi (US), Aardschok (Netherlands), Metal Hammer (Hungary), Rock Hard (Germany, France), Heavy Oder Was? (Germany), Scream (Norway), BW&BK (Canada), Hard Rock (France) and in countless webzines and fanzines. The band quickly established a solid fan base around the World. Zero Hour successfully toured Europe and performed twice at Prog Power USA, the largest prog-metal music festival in the World, in Atlanta. In 2003, fans were dissapointed when Zero Hour parted ways with Erik Rosvold. Both "Metamorphosis" and "The Towers of Avarice" were considered progressive-metal classics.
In late 2007, Jasun began writing material for Cynthesis. As the music developed Jasun could only imagine one vocalist to really connect to the material. " I've always been a fan of Erik's vocals and I knew his lryic writing would be a perfect match for the material." explains Jasun. After one phone call both Jasun and Erik were very excited to work together again.
The final piece of the puzzle was to find an amazing drummer. Jasun asked Troy what drummer he would like to work with. Without any hesistation Troy said "Sean Flanegan is the guy". Sean's been a long time friend and played drums on Jasun's 2000 instrumental release, Night's Pulse. Sean is best know for his amazing work with the Progressive Rock band, Enchant (Blink of an eye & Tug of War)
