In 2000, Vescera becomes a definitive member of the band and starts to share vocals with Andria. In quartet, they record the fourth self-titled album, "Dr. Sin II". In a previously unheard of attitude in Brazil, the band releases this album in a magazine with the history of the band. This version could only be purchased at newsstands. The album was received by fans and critics in general, with fuss and admiration, as Vescera and his timbre fit the group's compositions perfectly. Also featuring Brazilian guitarist Sérgio Buss (Steve Vai, Tritone), Jason Himmelberger and Joey Gross Brown on keyboards and Roland Grapow (formerly Helloween). The song “Time After Time” was still the soundtrack of Fórmula Truck racing in Brazil, which was broadcast at the time on RedeTV!
