Here’s some nifty symmetry for you: Two casino shows, both next Thursday night, are bringing classic rock legends to the Inland Northwest. Pick your poison. Steppenwolf’s 1968 single “Born to Be Wild” — best known for its inclusion on the Easy Rider soundtrack — still conjures images of free spirits barreling down the highway on motorcycles, every mile bringing them closer to the elusive American dream. (Fun fact: It was written by a guy with the stage name Mars Bonfire, which is awesome.) It became a generation-defining song, as did their tripped-out classic “Magic Carpet Ride,” with its feedback-laden intro and that spacy instrumental break. Original Steppenwolf frontman John Kay is still with the band, so you can still get a sense of what the band was like in its Woodstock-era heyday.
