There's a sequel coming for "Ziltoid the Omniscient." Devin Townsend said this week.

"Ziltoid the Omniscient" was released in 2007. It was a concept album about an alien named Ziltoid that travels to earth in search of the ultimate cup of coffee. It was a solo effort, and Townsend has revealed on Twitter that he is working on a sequel to the album.

"I began writing for 'Z2' about six months ago," Townsend tweeted. "Between all the ideas, there's close to 70 songs. Some are really good, but none are it. How do you not repeat yourself? How do you avoid being a caricature? How do I incorporate Ziltoid with what we've done and not just be silly."

In another tweet, Townsend revealed how far along he is on the project: "I'm proud to say that the ideas that are coming now are beginning to take the shape. The theme. It's so exciting. We start recording in May."

Last year saw the release of Towsend's "The Retinal Circus" CD/DVD.

Before "Z2," Townsend plans on releasing the album "Casualties of Cool" in May. He tweeted details about that as well: "'Casualties Of Cool' ... It's a bridge to the 'Z2' phase, (a) really important one to me."
