For 5 years, they were performing shows all over Texas, touring Spain and making an exceptional impact in Austin’s music scene. In 2019, Sefo returned to his home country of Spain. Kostamos and Sefo continued to collaborate on musical ideas and recordings via the internet. In 2016, Kostamos also became a member of the international rock band Bull y Los Bufalos.

These two different, but very passionate rock n’ roll projects, became friends and often performed shows together. Kostamos was asked to fill in for a few of Deann’s shows. Every time they were performing together, there was exceptional magic on stage. Soon enough, Kostamos joined her band and they have been performing together since then. In late 2019, the Deann Rene Band started recording their new album which is expected to be released in 2021. In 2018, a supergroup of many talented musicians in Austin formed the band Tex Zep, paying their tribute to one of the greatest bands of all times, Led Zeppelin.

In early 2020 Kostamos was in the studio recording a new EP with the band Rockwell Harrison, which is currently in the works and expected to be released in late 2021. Late in 2020, the exceptional flamenco guitarist Rojas, asked Kostamos to join him on a few experimental shows. The two musicians previously met each other on stage during a Deann Rene Band show, where there was an obvious chemistry. Soon they were sharing the stage again playing Rojas’s unique music and have since become close friends. Currently, Kostamos Yiacoumis and Caleb Rojas have joined forces to create a new band called Onomatopoeia, a project based on international sounds, ethnic melodies and Native American spirit.

In addition Kostamos has appeared as guest drummer for Austin artists such as Chris Duarte, John Gaar Band, Ulrich Ellison and Tribe, Erez, David Henderson and Jeff and the Jumptones.



A project based on international sounds, ethnic melodies and Native American spirit.
A Spanish flamenco breeze dances it’s way through ambient pathways, wandering around in the ancient temples and the rich culture of Greece. Blending a Mediterranean musical dream with the oriental dynamics of the Middle Eastern, that dream echoes deep in the Far West, awakening the indigenous spirit of the Native American land. A powerful mix of world music, held together by Latin soul and modern rock, bonded in the universal language of Blues from Austin Texas.
