Lidell is known^{[by whom?]} for layering tracks made with his voice into a microphone and performing the percussion and melody as a sequenced, beatboxing one-man band. Following the release of his 2008 album, Jim, Lidell commented,

I want it to be about music, I think every musician does. But I think inevitably it ends up becoming about personality, which is what gives rise to the music, so people want to make sure that they get a bit of both. The more things do well, the more people want to know why it does well.

His song "Multiply" was used on the television show Grey's Anatomy, and was also included on its second soundtrack. Another song from his album Multiply, "A Little Bit More", was featured in a series of commercials for the U.S. retailer Target.
