Hey, Mothership from Dallas, Texas has a three song Demo up for free download.
"Mothership is a tasty combination of 60's and 70's blues infused style riffs, teamed with the blistering guitar solos of the late 70's and early 80's, a rare 3 piece smelt of super sonic intergalactic Heavy Rock and Blues.
The gleam of the Mothership in the distant galaxy promised a future to music and mankind alike. Without the intergalactic journey, the legacy of rock music dies." (Band Bio)
