John Hinckley, who tried to assassinate Ronald Reagan in 1981, may have a new career as a musician.

Hinckley has a performance in Brooklyn, New York in July — and it’s already sold out. Tickets at the 450-capacity Market Hotel were going for $20 each.

Hinckley was released from a Virginia psych ward in 2016 after being acquitted by reason of insanity.

Since his release, he’s been posting videos of his original song and his YouTube channel has amassed 26,000 subscribers.
