Together with Led Zeppelin and Black Sabbath, pioneering rock band Deep Purple made up what came to be known as the “unholy trinity of British hard rock and heavy metal” in the early to mid-‘70s, with chart-topping hits on both sides of the pond like “Smoke on the Water,” “Highway Star,” “Space Truckin’” and “Hush.” For this concert at Costa Mesa’s Pacific Amphitheatre, they’re joined by Foghat, whose massive hits “Slow Ride,” “Fool for the City,” and “I Just Wanna Make Love to You” remain classic rock radio staples. In the ’70s, Foghat was one of the biggest touring rock acts in America and their native England, and their current lineup includes founding member Roger Earl, former Wild Cherry guitarist Bryan Bassett and lead singer Charlie Huhn (Ted Nugent, Humble Pie). Both seminal bands will play their biggest hits at this classic rock lover’s concert. Tickets include admission to the OC Fair.
