Lawrence Mumford’s music, published by eight different companies, has premiered in cities across the United States. Two movements from his Symphony No. 4 (Of Times and Seasons and Hope and a Future), recorded by the Czech Republic’s Janacek Philharmonic, have recently become a part of the broadcast libraries of the largest classical radio stations in Boston, Cleveland, Washington DC, Los Angeles, San Francisco, and other cities, and have been played repeatedly. This music is also available on Spotify, Amazon Music, Apple Music, and other streaming services..
