Rainbows Are Free is an American psychedelic doom band from Norman, Oklahoma, known for their heavy, hypnotic sounds and a psychedelic flair that is both entrancing and menacing. Formed in the late 2000s, the group quickly established itself as a force within the underground heavy music scene with a self-titled debut album "Rainbows Are Free" in 2008, which marked their sonic territory with a blend of sludgy, acid-laden grooves. As they evolved, their dynamic grew more complex and nuanced, without losing the raw edge that characterized their early work.

Their subsequent releases, "Believers In Medicine" (2010) and "Waves Ahead of the Ocean" (2014), further cemented their reputation for crafting dense, swirling soundscapes that draw listeners into otherworldly realms. With tracks like "Sonic Demon", "Like a River We Will Roll", and "Head Pains", Rainbows Are Free showcased their ability to balance melody with the weight of their sound, earning a dedicated following among fans of stoner and doom metal. The band's most recent work, "Heavy Petal Music", continues their tradition of mind-bending heavy music, with tracks like "Crystal Ball" delivering on the promise of a transcendental listening experience that reverberates well beyond the temporal confines of modern music.
