While most bluesy hard rock acts of the '70s and '80s hailed from the United States, there were several exceptions to the rule. Canadian singer/guitarist/keyboardist Pat Travers with his hard, edgy tone, rough and rowdy vocals, and barroom boogie aesthetic is a stellar example. Arriving during the reign of hard blues-rock guitar slingers such as Johnny Winter, George Thorogood, and Robin Trower, his eight-album run for Polydor from the self-titled 1976 debut through 1984's Hot Shot, netted seven Top 200 chart placements (all but one in the upper half) and two Top 40 singles, including the party anthem classic "Boom Boom (Out Go the Lights)."
