Lex has a varied musical output.The label is not focused on one particular genre (although most releases are alternative hip hop, alternative rock or electronica) and instead focusses on working with a small group of individual artists, supporting their work.

Lex albums are often collaborations between members of the label roster and musicians from elsewhere. These collaborative groups include Danger Mouse with MF Doom as Danger Doom, Boom Bip with Gruff Rhys as Neon Neon, Jneiro Jarel with Khujo Goodie as Willie Isz, Jneiro Jarel with MF Doom as JJ DOOM.

Recent and forthcoming releases include NEHRUVIANDOOM by Bishop Nehru & DOOM, Machine City by Circle Traps, WASH EP by High Lucia, Sour Soul by BADBADNOTGOOD ft. Ghostface Killah and the debut album from Nevermen (Mike Patton)

Lex packaging is striking and often elaborate. Much of the Lex sleeve artwork is created by Ehquestionmark. Other sleeve artwork has been created by ESPO, Kid Acne, James Jarvis, GHOSTSHRIMP & Yu Sato
