Having completed his philosophy degree, Costello engaged himself in university studies in music and was introduced to Steve Reich, John Cage and Karlheinz Stockhausen. In 2000 he began to release 12" singles on his own label Minimise and was signed by Force Inc. for his first album. Growing Up In Public utilizes new digital production and synthesis methods, sampling and dub techniques. This debut album displays a great degree of imagination and experimentation.
