Kostamos Yiacoumis was born on August 9, 1984 in Nea Halkidona-Athens, Greece. At the age of 7, he started his musical education by taking piano lessons. While he did not finish his piano studies, the fire of music was now burning strong inside him, and at the age of 15 Kostamos decided to study drums.


Kostamos began his professional career as a drummer in 2005 and collaborated with several notable Greek musicians and singer-songwriters such as Kostas Chronopoulos, Vox, Giannis Markopoulos, Manos Xidous, No Balance, Teresa Panagiotopoulos, Nikos Georgousakis / M51, KARMA, and The Secret.


He began teaching drums at Handrou Conservatory in 2007, as well as giving private lessons.


In 2010, Kostamos helped form the band The Secret, which was selected to participate in the EUROVOICE” contest. After several weeks of audience voting, The Secret were named the winners and their song “In the Arms of an Angel” was featured in the televised finale.

New start in Austin Texas

Kostamos moved to Austin, Texas (USA) in February 2013 to continue his musical career. In April, he became a member of the rock band One World (R)evolution. By the end of the same year they started the recordings for the album “Love Is the Answer”, which was released in 2017.

In the summer of 2014, Kostamos met the extraordinary guitarist and songwriter Jose Barragan (Sefo), who was performing all over the world as lead guitar player of the international artist Franco De Vita. Kostamos joined forces with Sefo and bassist Aaron Davis on Sefo’s own band and soon became as close as brothers. 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.

Bull y Los Bufalos

In 2016, Kostamos also became a member of the international rock band Bull y Los Bufalos. Led by Bull-Diego Avello, they performed to large crowds throughout Spain and Mexico before coming to Austin, Texas. They have continued to play many shows and large bike festivals, including the Republic of Texas Biker Rally, as well as other Harley Davidson events. They have released several albums and videos, and in 2019 had songs featured in the FX television series “Mayans MC”.

On August 31, 2019. Kostamos and the band Bull y Los Bufalos were awarded in several Spanish Rock categories at the MXD MAG (Maxima Distorzion Magazine) Rock and Metal Awards 2019.
-Best Hard Rock Band in Texas
-Best Hard Rock Drummer in Texas
-Best Alternative Rock Drummer in Texas.

In November 2019, Bull y Los Bufalos recorded their live show at the music venue “Come and Take It” in Austin TX. Songs and videos from this show have been released on social media as “Handmade - Live in Texas”.
2017 - 2018

In 2017, Deann Rene Band was the opening act for a Bull y Los Bufalos show. 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. With Kostamos on drums, Tex Zep have performed many sold out shows in the greater Austin area, offering an unforgettable experience to their audience.

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.

During his time in Austin, Kostamos has also played with many artists, bands and in music jams such as: Jocelyn Donegan, Gary Cain Band, Coleslaw & The Po’Boys, Mojo Jam, Rockwell Harrison, Bouza Boys and Top Choice.

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.
2021 - 2022

- After losing almost 2 years (2020-2022) of normal life with the worldwide Covid pandemic, the music industry has slowly started to come back.
- For most of 2022, Kostamos had a busy schedule.
- He started January with a memorable event when Austin’s esteemed Americana artist Guy Forsyth hired Kostamos to be part of a private concert for the Texas State Society that took place in Washington D.C. …next to the White House!
- In the following months, in addition to performing non stop in the Austin area and other Texas venues with the Gary Cain Band, Deann Rene and Tex Zep, Kostamos worked with many other bands and artists such as the legendary rock band Thunderosa, RJH, Jose Pasco, Jamie Krueger, Jeska and the Vanity Project and Mauricio Callejas. With Mauricio, he also recorded and released two songs and a video of Mauricio’s original songs, Desarme and Aun.
- In April 2022, Austin’s School of Rock hired Kostamos as an instructor for private lessons and as assistant director for some of their Performance Program shows and Summer Camps.
- At the beginning of Summer, Kostamos did a mini tour with the Gary Cain Band through Tennessee and Kentucky. At the end of July, he reunited with his friend and exceptional guitarist, Sefo for a mini tour of Spain. Among the shows with Sefo was a performance at the wonderful 4 day Pueblos Blancos Music Festival 2022, a festival in which Kostamos also performed with the Gary Cain Band.
- Unfortunately, in September this happy ride was interrupted by a hit and run motorcycle accident while on the way to a rehearsal with Tex-Zep. After a total of 2 surgeries in 3 months to repair a broken fibula in his left ankle, Kostamos is looking forward to returning to his musical families and friends and regaining the lost ground caused by the accident.

While Kostamos is on his way to recovery he has been working on booking upcoming shows, as well as planning the rest of the year with some exciting news!
Taking another step ahead, this time celebrates his 10 year anniversary in U.S.A. with an online store for merchandise and drumsticks, a new platform for product recommendations & drum lessons, and a new album release with Deann Rene!
