Marcos Coll was born Madrid (Spain) in 1976 but soon moved with his family to Santiago de Compostela, in the northwestern Spanish region of Galicia. He started playing the harmonica at the age of 13, influenced by his musician uncle and by Spanish blues harp legend Ñaco Goñi. After playing with different amateur bands, such as the Red Bues Band, he formed his first professional band called Bluerags. In 1999 Coll moved back to Madrid to join the most famous Spanish blues band at that time, Tonky Blues Band. With this band, at the age of 21 he had the opportunity of touring and recording with rock and blues legends like Mick Taylor (Rolling Stones ) or Buddy Miles (Jimmy Hendrix Band of Gypsys) and even did a blues gig with Tom Jones(!).

After those years of great experiences, Coll was ready to form his own band, Los Reyes del KO, along with his soul brother, Adrian Costa. Los Reyes del KO (literally, The Knockout Kings) soon became one of the top blues bands in Spain and Europe, earning awards and recognition, sharing bills around the world with such all-time greats as Buddy Guy, Johnny Winter, Chuck Berry, John Mayall, Solomon Burke, the Animals, Robert Cray and the Fabulous Thunderbirds, and even appearing in high school music textbooks in Galicia

In 2004 Marcos Coll moved to Berlin, where through well-known German blues musicians like Chris Rannenberg and Micha Maass he soon became part of the blues scene in the German capital.

As a studio musician he has recorded with nationally famous Spanish bands such as Siniestro Total, and has recorded music for TV and silent movies.

His new record was produced by Jairo Zavala (Depedro) at Infinity Studios where he revisited his roots of Galician, Manchego and Latin music and where most of the songs are original compositions.
