What is Simbioza

When music turns into adialogue

Two instruments. Two characters. One stage.

Simbioza is a Bulgarian music project that brings together the elegance of the classical piano and the power and dynamics of the drums.

There is no soloist and no accompanist here. The two instruments are equal partners — sometimes they complement each other, sometimes they challenge each other, but they always make music with character.

From delicate melodies to explosive rhythms, from classical masterpieces to rock legends — every performance is a new take on the familiar.

Simbioza does not just perform music. It reinvents it.

Who we are

Two characters. One passion for music.

Different temperaments. A shared musical language.

Piano Elegance with character

Classical virtuosity, artistic freedom and genuine emotion.

Valeria Valkanova combines the elegance of the classical piano with the courage to step beyond traditional musical boundaries.

Her performances move effortlessly from tender lyricism to captivating energy, where the precision of a classical musician meets the freedom of the contemporary stage.

In Simbioza her piano does more than sound — it tells, provokes and leads the musical dialogue.

“For me, music begins where the notes end and emotion takes the lead.”

She began studying the piano at the age of six. She graduated from the “Prof. Vesselin Stoyanov” National School of Music in Ruse and the “Prof. Pancho Vladigerov” National Academy of Music in Sofia. She has won awards at national and international competitions, including “Emanuil Manolov”, “Young Musical Talents” and “Franz Schubert”, and has taken part in masterclasses with Evan Hirsch, Sally Pinkas, Paolo Pollice, Ludmil Angelov and others.

Drums Rhythm without compromise

Energy, precision and a stage presence that does not go unnoticed.

With more than 30 years of professional experience, Radoslav Slavchev turns the drums from a rhythm instrument into a soloist in their own right.

His style combines technical mastery, musical daring and a feel for the show. Every performance carries his signature energy, attention to detail and drive for constant improvement.

In Simbioza his drums do more than keep the beat — they challenge the piano, shift the dynamics and turn every piece into a musical adventure.

“Every day I play something new that I couldn’t play yesterday.”

His professional path has taken him to stages across Europe and the Middle East. Much of his career is connected with Dubai, where he led his own band. He has also worked with established rock bands in Bulgaria. His personal acquaintance with Virgil Donati has contributed greatly to his professionalism and technique.
