Erik Satie was an eccentric French composer born in 1866. He worked with artists like Picasso and anticipated many avant-garde trends. Satie had an unconventional personal life and compositional style, pioneering minimalism and deviating from traditional harmony and notation. He founded his own religion and pushed away from relationships and trends to develop a detached, "moving away" orientation. His large-scale piece Vexations required 18 hours of repetition to perform and caused hallucinations in performers.
