Born in the suburbs of Leiden, The Netherlands (just outside of Amsterdam), Dennis Leeflang picked up a pair of drum sticks for the first time at age 8, joining a local marching band. Once in high school, the explosion of grunge and rock music in the early 90’s prompted the then teenager to beg his parents for a drum kit. At age 13, Dennis was practicing drums 8 to 12 hours a day and quickly caught the ear and eye of local bands and musicians. In 1996, having just turned 17, Dennis was a founding member of Within Temptation, Holland’s biggest musical export product since The Golden Earring. After successful collaborations with other Dutch bands such as Sun Caged and Epica, Dennis traded windmills for skyscrapers in the early 2000’s, after having met guitar hero Ron “Bumblefoot” Thal on a vacation to New York City and realizing the musical opportunities on the other side of the pond. Upon his arrival in the Big Apple, Leeflang became Bumblefoot’s full-time drummer, recording three full-length albums since 2005 and touring all over the world. Next to his work with Bumblefoot, Dennis collaborated with dozens of local NYC bands and musicians in genres ranging from jazz to metal, with the majority being many of the fine singer-songwriters New York is famous for. Apart from touring with various artists such as The Saturnine, Ted Poley (Danger Danger) and Lita Ford, Dennis built his own recording studio in Queens in 2007, enabling him to collaborate through remote recording as well as record music with local musicians. With the major shift the music industry was experiencing, owning his own recording studio and offering remote drum sessions proved to be a golden ticket. With major label budgets becoming a thing of the past, Dennis was able to offer quality drum tracks at a fraction of traditional budgets, staying ahead of the game.
Between his own studio and many of the famed New York recording studios like NoHo and Water Music, Dennis has collaborated with musicians such as Angus Clark (Trans-Siberian Orchestra, Joe Lynn Turner), Ted Poley (Danger Danger), Shane Gibson (KorN), Mike Orlando (Adrenaline Mob), Tiffany Giardina (Disney), Morgan Clamp, Milan Polak (Falco), Kip Winger (Winger), Barend Courbois (Vengeance, Blind Guardian), Richie Castellano (Blue Oyster Cult), Fabio Trentini (Guano Apes, H-Blockx), and Anneke van Giersbergen (The Gathering, Devin Townsend), as well as some of the industry’s most celebrated producers, including P.J. Bianco (Jonas Brothers, Demi Lovato), Nick Sansano (Sonic Youth, Ice Cube, John Spencer Blues Explosion, Galactic) and Easy Mo Bee (Miles Davis, Notorious B.I.G., 2Pac, Wu-Tang Clan).

in 2015, Dennis relocated to Los Angeles, where he has since toured, performed and collaborated with artists such as Dilana (Rockstar Supernova), Mitch Perry (Cher, Edgar Winter), Kenny Kanowski (Steelheart), T-Bone Andersson (Gov’t Mule), Francesco DiCosmo (Evanescence, Thin Lizzy) and Eric Dover (Slash’ Snakepit, Jellyfish, Alice Cooper).

Apart from performing and recording, Dennis has been a drum instructor since 2000, teaching private drum lessons, clinics, masterclasses and workshops all over the US, Europe and Russia. When not on the road, Dennis is available for private drum lessons in Los Angeles.

Dennis proudly endorses Q Drum Co. drums, Paiste cymbals, Promark sticks, Evans drumheads, Drumtacs and Ahead Armor Cases.
