The Alchemist

Ignoring the coastal feuds that dominated hip-hop for most of the '90s, the Alchemist (born Alan Maman) began his career in L.A. (he grew up in affluent Beverly Hills) and ended up in New York City. As a teenager, as part of the duo the Whooliganz (with Scott Caan, son of James) and the greater rap collective the Soul Assassins (with Cypress Hill, House of Pain, etc.), he released the single Put Your Handz Up on Tommy Boy in 1993, though the Whooliganz's debut full-length, Make Way for the W, was eventually shelved. The Alchemist continued making beats, however, working with and learning from DJ Muggs on 1995's Cypress Hill III: Temples of Boom as well as with childhood friend Evidence of Dilated Peoples. After moving to New York to attend college, Al hooked up with Queensbridge duo Mobb Deep, producing the songs "The Realest" and "Thug Music" from their 1999 record Murda Muzik, a collaboration that led to work with Pharoahe Monch, Royce da 5'9", Fat Joe, Defari, Freddy Foxxx, Ludacris, Big Daddy Kane, and Ghostface Killah, and even rock acts like Linkin Park and Morcheeba. In 2004 the Alchemist released his first solo full-length, 1st Infantry, which, besides featuring his own beats, also had him rapping alongside Stat Quo, the Game, Lloyd Banks, Mobb Deep, and Dilated Peoples, among others, and in 2005, after Eminem's DJ Green Lantern left the Anger Management 3 tour, the Detroit rapper hired Al as his replacement. In 2006 the Alchemist showcased his work with a pair of mixtapes of previously released and unreleased material, The Chemistry Files and No Days Off.
