+1 for Harry Parch. Here's a good introduction for new people [1]. I'd add in Lou Harrison [2] and Tristan Murail [3] Lou Harrison was heavily influenced by Gamelan music, and Tristan Murail is one of the founders of spectralism, which uses spectrograms of individual instruments to build distinct harmonies by having orchestral instruments play the harmonic series as shown on the spectrogram. They stretch this idea even further by adding in "harmonics/overtones" that are not shown on the spectrogram to create dissonance.
