By 1980, Rush was experiencing the mid-point of what would be their golden period of recording (1976-1982). Released in January that year, Permanent Waves was a transitional exercise that moved them further from the "prog-rock" lump-labeling and pointed the way for their next masterpiece the following year, Moving Pictures.
Peaking at No. 4 on the Billboard Album Chart, Permanent Waves spawned such perennial concert staples as "Freewill" and "Spirit of Radio." Well-beyond the power-trio of old, Geddy Lee, Alex Lifeson and Neil Peart each contributed equally, with multiple instrumentation and arranging approaches. An undisputed rock classic.
