Mitchell Peters

Mitchell Thomas Peters (August 17, 1935 – October 28, 2017) was a principal timpanist and percussionist with the Los Angeles Philharmonic Orchestra. He composed well-known pieces for the marimba such as "Yellow After the Rain" and "Sea Refractions"; it is said that these works were composed because Peters felt that there was a lack of musically interesting material that would introduce his students to four-mallet marimba techniques.
