Query: Winding the Sky

O2 will penetrate and transport any true rock fan to another level. The band's skillfull use of layered guitars, driving bass, expressive melodies and inventive drumming and keyboards create a full, rich sound. The vocals are powerful and passionate with angst-ridden and thought provoking lyrics that are loaded with imagery. This is an amazing album!
