„Sleepless will keep you up at night with its hard edged bluesy riffs, mesmerizing groove, and flat out ass-kicking swagger. Join in on the insomnia of rock n' roll paradise, you don't want to wake to a reality void of Diamond Skull. High praise.“
– Bucky Brown (Doom Charts, Ripple Music)
„Straightforward, but with great attention to detail, this bluesy desert stoner goodness will make your morning coffee taste heavenly. Favorite track: Secret Planet.“
- Henrik Thøgersen (Bandcamp)
From start to finish this band delivers everything I could ask for in a Metal band...haunting, melodic, incredible musicianship and the vocals just blow me away. Just amazing Favorite track: Dark Wings.
