The band - which is comprised of Al Crespo (vocals), Martin Ries (guitar), Pascal Alles (guitar), Lukas Mittler (bass), and Alexander Ries (drums) - couldn't have picked a better/knowledgeable producer, who certainly knows a thing or two about classic '80s metal himself!former Scorpions drummer Herman Rarebell.

"It was a real pleasure to work with Unbreakable," says Rarebell. "They could be the next SCORPIONS! That is what I think and feel - I had a lot of fun producing them. America!get ready for Unbreakable!"

Once the album drops, Unbreakable plan to hit the road hard, showing the world that they can rock and party with the best. "You can expect a high energy rock show and hard power chord guitar riffs with melodic solos, a high metallic voice and driving drum rock beats. We feel like home wherever the stage is!"
