Rocker Wayne Coyne is to launch an adult-themed comic book at this coming weekend's (18-21Jul13) Comic-Con convention in San Diego, California.

The Flaming Lips frontman's first ever comic venture, The Sun Is Sick, will go on sale at the annual nerd spectacular.

An extremely limited print run of the "psychedelic fantasy in classic comic book form" is expected to sell out at the San Diego Convention Center.

Future copies will be available from 22 July (13) via the Flaming Lips website.

Announcing the comic book's release on Monday (15Jul13), a spokesman for Coyne tells Wenn the singer's latest venture isn't for everyone: "The Sun Is Sick may be a comic book but make no mistake; this is not suitable for children and depending on what sort of person you are, it may not be suitable for some of you non-children either.

"If you have doubts at this moment then The Sun Is Sick is not for you. If you happen to be a Lips fan that has enjoyed Wayne's beautiful artwork in the past and like adult-themed comic books then by all means this instant collector's Item is waiting for you."
