Holly (born Miguel Oliveira, 1995) is a Portuguese-born producer and DJ working between the Lisbon area and Los Angeles. He works primarily in bass music and drumstep, and his releases and mixtapes are described as bass-heavy electronic music. His 2020 mixtape Dark Skies & Holy Grail is a named release in his catalogue.

Oliveira began making music at 18 and moved from producing bedroom beats to professional work that spans club material, mixtapes and artist production. Early public milestones include winning the inaugural A-Trak Goldie Awards Beat Battle in 2017, a result that foregrounded his beat-making and arrangement skills. In recent years he has been profiled as LA-based while retaining ties to Portugal.

Holly’s production style centers on weighty low end and tight, punchy percussion. Working in drumstep and broader bass music, his tracks emphasize half-time or syncopated break patterns layered under dense sub-bass and textured synth work. Mixes and mixtape sequencing lean toward contrast — hard low-frequency design against clipped, staccato drum edits — and his arrangements often deploy chopped breaks and pitched bass drops to create that drumstep swing without losing club clarity.

As a producer he has a demonstrable record of collaboration across genres. He co-produced on Baauer’s Planet’s Mad, an album that went on to receive a Grammy nomination for Best Dance/Electronic Album in 2021. He has also produced for artists across hip-hop and K-pop scenes, including CL, Gunplay, A$AP TyY, OG Maco, UnoTheActivist, Jay Park, Lee Hi and Portuguese artist Slow J. Those credits show a workflow that adapts bass-driven production to vocal-led tracks as well as instrumental club material.

On the live and festival side, Holly’s work has reached international stages: he has toured and performed at major events including Coachella, EDC Las Vegas and EDC Korea. His mixtapes — notably Dark Skies & Holy Grail (2020) — function as both artist statements and DJ tools, presenting his club-ready edits alongside heavier production pieces.

Key professional connections and recognitions include the 2017 A-Trak Goldie Awards Beat Battle win and the co-production credit on Baauer’s Planet’s Mad (Grammy-nominated, 2021). Public biographical detail beyond these credits is limited, but the verified record shows a producer who moves between club-facing drumstep/bass music and cross-genre production work for international artists.
