HD4000 is actually two people: Odeed and Wish. After producing breaks together under various aliases since 2003, they discovered dubstep one evening in San Francisco - playing breaks at a underground party for a close friend of theirs. Odeed and Wish were the only act that night that wasn't playing dubstep, and after their set, they stayed to hear what it was all about. They were pretty impressed, then after hearing some of 6Blocc's tunes they decided to give it a go and made their first song as HD4000, "Guess Who".
