After exiting both Dio and Dokken, he and former War & Peace mate, Tommy Henriksen, began working on a modern rock project called Underground Moon, for which Pilson decided to assume the pseudonym Dominic Moon. The album, which included a cover of Midnight Oil's "Beds Are Burning", was released in Europe and Japan in 2001 and Pilson put together a short-lived live band and performed a handful of L.A. club shows. The album saw a limited edition re-issue in 2008 through Polish company Metal Mind Productions.
