In New York, Warner expanded his repertoire to commercial soundtracks, drumming on the Sega Genesis "Mortal Kombat" TV theme, a Miller Lite TV and radio campaign, and numerous other commercials. From 1995 to 1996 he was a member of Harry Slash & The Slashtones and the short-lived New York band The Horsemen. During the late '90s, Warner found himself maintaining dual-residency in both the London and New York music scenes as a session drummer. He continued his contributions to Ten Wings Music through his work with Motorbaby, and began working with up-and-coming New York rock band Queen V on Skyhigh Records.
