Hólmar discovered his passion for music while putting together playlists "live" at parties all over Reykjavik's bustling underground scene. He then moved to New York, where he hit the ground running and started throwing rollicking parties all over the Big Apple. He formed the infamous Crack & Speed Records with his good Parisian friend Jef-k. On C&S he debuted his music as a part of the “super” group Mr. Negative & The Spencer Filipsson Experience. During one of Holmar’s parties at a former brothel on the Lower East Side, he met Greg Oreck and shortly thereafter founded “Thugfucker”. After working together for a few years, during one hot summer night in Hólmar’s studio in Williamsburg, they created “Disco Gnome”. This record ended up being the first release on Life and Death Records and launched them into the international scene along with Tale of Us and Dj Tennis. He spent next years touring with Greg and fellow mates at Life and Death causing general mayhem and good times at clubs and festivals all around the globe. In recent years in addition to his work with "Thugfucker" he has started new collaborations. He co-founded “Lovestruckk” with Nico Stojan, “Theory of Light” with Brian Cid, “The Birds Fly South” with Maxxi Soundsystem and his first release in 2018 will be an E.P with L.A’s Jon Charnis. He is also a part of a new dj collective the infamous "Twister Sizterz". In 2018 we will see his departure from “Thugfucker", launching his solo career.
