In the early ’70s, Grand Funk Railroad barreled onto the rock scene like a runaway train, selling out stadiums and collecting hit records along the way. In just seven years, they became the first American band to score 10 consecutive platinum albums. Always full of energy and often shirtless, they had a muscular sound that featured powerful vocals, bone-rattling bass lines, in-your-face guitar riffs and thunderous drumming. It was loud, heavy and full of soul. After nearly 5 decades, these guys still put on an epic show – but this time, with their shirts on.
