Lester is a producer and DJ. He gradually invented the electronic and nostalgic emo style of the 2000s, placing his shy voice and the texts of his diary on pop and depressing melodies. He is a fan of T.a.t.u. and Marilyn Manson, but his songs bring together Grimes pop, Purity Ring and TR/ST, mixed with more hardcore sounds, like those of the raves of the 90s.
