Before landing on UncertainFM for its weekly debut broadcast Sundays at 3 p.m. EST, Boston Emissions began airing on WBCN some time in the 1980s. Throughout this time, the show has been instrumental in introducing and establishing thousands of bands from around Boston and New England. The mission of the show has always been to expose and support independent bands and artists of varying rock styles from the region. Anngelle Wood became host in 2008. A year later, upon the demise of the rock radio behemoth WBCN, Boston Emissions moved dial positions to 100.7 WZLX where the show aired until May 2018. In September of the same year, host Anngelle Wood took the show entirely online where she programs the show, live streams, hosts events, studio sessions, and books shows with a focus on new music discovery.
