Arriving in the United States from Bulgaria at the age of 21, Rado Stefanov dived into further exploring his affinity to progressive house, melodic techno as well as rock music production. With guitar as his main instrument he was a member of The Hooplas performing local venues in Maryland during 2014-15 and later on after moving to San Francisco his focus shifted towards progressive house, which eventually led to the formation of Soundproof US in 2021 with Serbian tech house DJ and producer NEM. The recognition of the DJ collective launched a series of shows in some of the most iconic venues in San Francisco, including Audio SF, The Midway, Halcyon SF, 1015 Folsom, Public Works and more, opening for acts, such as Oliver Smith, Shouse, OXIA. In November 2022 Stefanov released his first single "Lighthouse" under his artist name Readol on the french label Teoxane Production. Over the 2010's the influence of Anjunadeep, This Never Happened, Mostercat Silk, Odd One Out, Meanwhile and other melodic house and techno labels helped shape Stefanov's music vision. In October 2023 a 2 track EP "Milieu" set the continued relationship with Teoxane Production. Since the initial releases and due to his versatile compositions, Stefanov has been involved with other labels, including Therefore Records, Droid9, Progressive Vibes Music, Immersed Recordings.
