A-Tack is the first Hip-Hop group to come out of Milwaukee, Wisconsin. It consisted of DJ, emcee, and producer DJ Peechy (later shorted to Peech), DJ Special K, and emcee T.A. Wiz. They released a couple of singles, each getting 200-300 pressings. They recorded a handful songs and performed local shows in the mid-late 80's. They are credited as pioneers who opened the doors for other artists and groups in Milwaukee, such as Kidd Crab, DJ Blade, MIDI, 20/20 Boys, Kali Tribe, Strick Luv, Female DSC, all of them having collaborated with DJ Peechy.

T.A. Wiz, a highly respected and influential emcee, was later senselessly murdered in cold blood. Peech traveled to Atlanta, changed his stage name to Speech, and started the multi-platinum, Grammy award winning Hip-Hop collective, Arrested Development, who still actively record and tour to this day. He also has a successful solo career, wrote the book "What Is Success?", and starred in the film 16 Bars. Special K joined Speech and served as Arrested Development's production manager and DJ, and produced some of their songs in the 90's. Special K now goes by DJ Kemit and is a successful producer and touring DJ.
