Sounds like Angra, basically it's Angra vocalist Andre Matos and rhythm section Luis Mariutta and Ricardo Confessori, with Hugo Marietta on guitar, essential for fans of Angels Cry, Holy Land & Fireworks era of Angra.
I bought this on AMZ recommendation and for once it failed completely. THis is only a poor Dream Theater clone, nothing special in this CD. It was a drag to listen to it and for good measure I tried a second and third time, but it did not change anything. The only good thing they have is the singer, who would advantageously replace LaBrie in DT (hopefully this singer can play on tune live, unlike LaBrie). Toss.
