Pitchfork darlings Free Energy refab American rock ‘n roll with a twist on the old familiar, falling somewhere between the earnest riffs of Springfield’s “Jessie’s Girl” and Spoon’s enthusiastic beats (long before they plateaued at mediocre with Ga Ga Ga Ga Ga). “Dark Trance”, off their debut Stuck on Nothing, possesses an inherent charm comprised of wailing riffs and straightforward poetics. “Something in Common” is the perfect mix of upbeat and heartfelt (reminiscent of what Sugar Ray’s “Every Morning” might have sounded like if they knew what indie rock was). “Power pop” for the masses, Free Energy sets to kick start your weekend with a bang pop premised by quirky jams compliments of Sweatheart.
