The band is in peak form and also churned out the single "Point of Know Return," which is still played daily on classic rock stations. While their pop-oriented approach and standard rock guitar sound helped define the classic rock sound of the '70s, careful listening reveals that this band's talent goes beyond colleagues such as Bachman-Turner Overdrive and Boston. Their arrangements and time signatures more accurately reflect the music of Yes and Emerson, Lake & Palmer. "Paradox" and "The Spider" are both excellent examples of their progressive approach. Unfortunately, the band always struggled to maintain a healthy balance of progression combined with pop. That made for such awkward moments here as "Portrait (He Knew)" and "Lightning's Hand." Yet despite the minor inconsistencies and a dated sound, their interplay and superior musicianship make this both an essential classic rock and progressive rock recording.
