Mason is the composer for sleep-aid music SleepCycle Sounds. SleepCycle Sounds is a music-based audio product that is designed to help you fall asleep, and stay asleep. It is composed at the tempo of an average adult's resting heart rate, and has a heartbeat to audibly help slow your brain down from a long, active day. The music is composed to help guide you throughout each of your sleep cycles. Below, you can hear selected tracks from the debut alum Sleep Cycle One.
