Aaron Lumley (1981, North Bay, Canada) is an Amsterdam-based double bass player and improvising musician. Working primarily in the fields of free jazz, post rock and 21st century composed music, Lumley is an exploratory musician who embraces the huge sonic and expressive power of the acoustic contrabass. He plays on gut strings tuned in fifths, one octave lower than a cello, for their raw tonality and deep resonance. Musically-active in Canada since the mid 2000s, Lumley has recently relocated from Montreal to Amsterdam, NL to join its thriving artist community.
