Summoned from the underground the members of death metal band Tiwanaku have gathered to create a line up to destroy stages in 2023 and beyond. Backing up their new album Earth Base One to be released November 4th 2022 by Unorthodox Emanations. The new death metal division of Avantgarde Music of Milan, Italy.

Formerly of Nocturnus, Vocalist/Guitarist Ed Mowery formed this new line up of awesome musicians. Starting with Ryan O'neill on the keyboards and orchestrations. Ryan is a master of his instrument as many of you will hear on Earth Base One and live. Sean "Hairy" Valentine on Guitars is a 7 string beast of a guitarist. The live guitar mixture of Sean and Ed will be quite a site and sound for everyone to behold. Sean has brought a lead guitar sound to Earth Base One that no one else could have. Hairy and Ian play in another band together called Plague Rider. Ian Spencer is the drummer for Plague Rider and bassist for Tiwanaku. The bass sounds Ian provides are phenomenal and since he is also a drummer him and our newest addition to the band, Gabriel Lewandowski, our new drummer, will be quite the bad ass rhythm section together on stage. Gabriel has played with many top notch musicians and toured and/or recorded with the likes of Resurrection, Hellwitch, and many more. Gabe is a professional drummer and fits in perfectly with the band.


The band will come together in the next few months to work on their second album before touring many places on the planet in 2023 to promote Earth Base One. The sky is not the limit for this band. Tiwanaku will spread its music across the galaxy and through the many other dimensions of the universe. Expect to see Tiwanaku live in 2023. Confirmation of live appearances and more to come...
