Angular Perceptions is the debut album by the American progressive metal supergroup Thought Chamber. The album received high praise from Sea of Tranquility webzine. Reviewer Murat Batmaz voted it the best debut album of 2007, comparing Ted Leonard's vocal style to Kansas and describing the music as " whimsical, with plenty of slap bass a la King's X, and [...]intense groove-inflected riffage and vintage 70's prog, throwing in eastern scales and eerie minor chord progressions."
