Happily I noticed during my holiday visit to Amsterdam that at the same time Dekmantel Festival 2016 (http://www.dekmantelfestival.com/) was going on in Amsterdam. I picked up from the program Alessandro Cortini performance in BIMHUIS. He had this minimal setup with iPAD working as a sound source and a selection of guitar effects that he used extensively to processing the sound. He created these beautiful soundscapes and little melodies/harmonies with delays, pitch-shifting, reverb and distortion. Distortion can be very beautiful when used deliberately.
