His career began in the mid 90's as part of 1st Down, which consisted of Phat Kat on vocals and Jay Dee on production. The group was short lived however, possibly because of insufficient support/promotion from their label, Payday, but the two continued to collaborate on many occasions afterwards, starting with an appearance on "Fat Cat Song" and it's remix, from Slum Village's Fan-Tas-Tic (Vol. 1).His first full-length album, The Undeniable LP was released on June 22, 2004, on Barak Records. It featured appearances from Slum Village, Dwele, Big Tone of 87 Wasted Youth, and Obie Trice. Kat released a 12-inch single in late 2006 for the song Cold Steel produced by J Dilla, he then followed it with his latest LP, Carte Blanche, on April 24 on Look Records. The album has proved to be Kat's most universally acknowledged effort yet. Now it's 2015 and he's back from his hiatus with Re-Dedication To The Suckers, a 7 song double album with a USA and European version all produced by Agor, a hot up and coming producer from the UK with features from Guilty Simpson and Elzhi.
