The 1980s was a period when hair metal bands like KISS and Van Halen began to evolve into genres like hip-hop and alternative rock. These bands were playing stadium rock with a heavier edge and emphasized their flamboyant make-up and teased hair. Ratt peaked in the mid '80s due to their perfected glam rock aesthetic. The band's 1984 debut album, Out of the Cellar, fully nails the genre blueprint. Twisted Sister frontman Dee Snider is considered the poster man for hair metal, while Poison was like a glam version of Van halen. Mötley Crüe is considered one of the most metal bands in the glam rock/hair metal era.
