Mark Dresser has been actively performing and recording solo since 1983. At the core of his music is an artistic obsession and commitment to expanding the sonic and musical possibilities of the double bass through the use of unconventional amplification and extended techniques. His solo works include the DVD/CD/booklet triptich Guts: Bass Explorations, Investigations, and Explanations (2010) and CDs UNVEIL (2006) and Invocation (1994) feature the music evolving out of this research. A chapter on his extended techniques, “A Personal Pedogogy,” appears in the book, ARCANA (Granary Press). Dresser has written two articles on extended techniques for The Strad magazine: “Double Bass Harmonics” (October 2008) and an “Introduction to Multiphonics” (October 2009). Dresser presented a lecture/demonstration titled “Discover, Develop, Integrate: Techniques Revealed” at the 2009 International Society of Bassists convention, where he curated a New Music Summit featuring lectures, performances, and panel discussions on improvisation and contemporary music performance.
