Due June 23, the band's self-titled debut album includes guest appearances by Def Leppard vocalist Joe Elliott, Whitesnake's David Coverdale, Sex Pistols/Manraze drummer Paul Cook, and Girl/Manraze bassist Simon Laffy.

Delta Deep formed from a series of jams between Collen and Blackwell-Cook, who were eventually joined by DeLeo and Robinson. "Blues was created out of something completely different from what we hear today," explains Collen. "I grew up listening to rock music but then I found out it was all based on blues. Jimmy Page, Keith Richards, Ritchie Blackmore, Jimi Hendrix, all of those guys….they got it from the blues.

"When I hear Debbi sing, I can hear the pain. She's an incredibly beautiful 62 year old black woman who has been through things and she can sing through her pain. Not everyone can do that and not everyone sounds like Debbi."
