The American trumpeter and multi-instrumentalist Jon Hassell, who died in 2021, was an international legend despite never having managed a popular breakthrough, mainly due to the fact that he almost never gave himself to the public. Jon Hassell was a musical visionary and pioneer, one who was inspired by ambient sounds and new music. He appreciated the music of avant-gardists such as Stockhausen, in whose Cologne school he also studied. He came into contact with Terry Riley and his minimalistic music early on and played on his first albums. Hassell was also a musically driven person, someone who had to get to the bottom of styles. Thus, he was intensively involved with Far Eastern, but especially Indian music. Using the ingredients he learned, he created a completely new way of playing on and with the trumpet. He created language-like modulated air currents flowing through the instrument to produce seemingly alien, microtonal sounds.
