Born in 1999 into a musical family, Leo Asal discovered his talent for drumming at the age of four. He quickly won numerous awards, including at the “Jugend Musiziert” and “Jugend Jazzt” competitions, both in ensemble and solo categories. With his versatile playing style, the “ZIRP” scholarship recipient established himself as one of Germany’s rising young drummers in jazz and pop. His music projects and tours have taken him to renowned venues and festivals in Germany, such as the ELBJazz Festival, Deutsches Jazzfestival Frankfurt, Jazz Baltica, Leverkusener Jazztage, Festspiele Mecklenburg-Vorpommern, Alte Oper Frankfurt, and internationally to Greece, Ecuador, Spain, Portugal, France, Romania, and Egypt.

From an early age, Asal developed a passion for jazz and hip-hop, which was further nurtured during his studies at the Mainz University of Music under Hendrik Smock. There, he learned from renowned jazz musicians such as Jesse Milliner, Sebastian Sternal, and Claudius Valk. He had the opportunity to perform with distinguished jazz artists like Emil Mangelsdorff, Diane Schuur, Dominique DiPiazza, and Nathan East. During his time in Mainz, he was also engaged as a drummer and musical director for the Loft Arts production series. Many projects linked to this brought him together with rap and R&B artists such as Megaloh, OG Keemo, MAJAN, Monet192, Lary, Teesy, Rola, Kelvyn Colt, Manuellsen, and more.

In 2019, Asal moved to Cologne, where he completed his studies with Prof. Jonas Burgwinkel and Alex Vesper. Since then, he has been a member of several touring bands, including the Jakob Bänsch Quartet and The Jakob Manz Project, and collaborates with Cologne-based singer Ketzberg. In 2021, he released the album Ein Tag wie ein anderer in collaboration with bassist Charly Härtel. Since 2022, Asal has been a regular performer at the Smooth Jazz Festival in Portugal, Spain, and France, sharing the stage with jazz legends such as Gerald Albright, Eric Marienthal, Everette Harp, Paul Jackson Jr., Michael Lington, Tom Browne, and Eric Darius.

Additionally, Asal founded the duo YAMUNA with keyboardist and beatmaker halfpastseven, exploring the artistic connection between humans and machines. Their debut album Focus & Distraction was released in 2024 under the Amsterdam-based label Wicked Wax, blending electronic elements with free improvisation.

From 2023 to 2025, Leo Asal was a member of the Bundesjazzorchester.
