T. Rex are synonymous with glam rock, but they were also subtle sonic chameleons. Early tunes like the acoustic “Summer Deep” exude the forest-nymph vibes of Marc Bolan's psych-folk days, while “Visions of Domino” reflects the disco strings and funk beats that pop up on their final albums. The band also loved rockabilly, which bubbles to the surface on the eccentrically bopping “Baby Boomerang.”
