There’s another subgenre to add to the growing hip-hop dictionary: Hyphy. The more up-tempo Bay Area cousin of Crunk, Hyphy is a high energy, aggressive street style that’s become a way of life for many young people in the area. And it’s not just about the music: Hyphy is a full-blown, self-proclaimed movement that’s equally characterized by frenetic dancing (known as “go dumb get stupid” dancing) completely void of inhibition or self-control. These are three Hyphy artists you should know:

E-40: One of the “founders” of Hyphy, E-40’s upcoming twelfth release My Ghetto Report Card is being produced by King of Crunk Lil’ Jon. The video for the first single “Tell Me When to Go” is expected to really introduce the world to the Hyphy movement, but My Ghetto Report Card CDs will also come with a documentary about the Hyphy movement.

Keak da Sneak: Oakland artist Keak da Sneak was part of 3XKrazy in the mid ’90s and has since gone on to develop his career as a solo artist. His “Super Hyphy” track featuring E-40 is a hit in the Hyphy movement.

The Federation: This MC team of Doonie Baby, Goldie Gold and Mr. Stres has also put Hyphy on the map with the home-grown hits “Hyphy” and “Go Dumb”. Now it’s all eyes on this style they’re calling a movement.
