After a decade of increasingly complex and fantastical prog-rock, Rush entered the Eighties looking for new influences. "The Spirit of the Radio," from 1980's Permanent Waves, found the Toronto trio dabbling in reggae rhythms. 1981's Moving Pictures took things even further, as the album-closing "Vital Signs" is built on Alex Lifeson's off-beat guitar skanking and Neil Peart's percolating drum part, both heavily indebted to traditional reggae patterns. The result is not far from the Police's work of the era. D.M.
