T.T is famous for his hour long house mixes and new style in mixing Persian dance music. Ali Seifoddini (Alex Seif) started his work since 2004 as DJ T.T. His artistic name T.T stands for Tunnel Trance. Back then it was not possible for musicians to perform live or in any public without legal authorization. For this reason he started his way with underground music which is now very powerful and popular in Iran due to restricted laws. Since Trance music was very demanding, and House music was not as popular as nowadays, DJ T.T started in that style. After 2 years, he continued his work with more essence of house music involved in his works. DJ T.T’s curiosity in house mixes made him one of the best Persian DJs ! It is not unpredictable that in 4 years he will become one of the top 10 DJs in the US.
