About

Grim Reefer fest is an annual grassroots DIY heavy music festival created and hosted by members of Haze Mage and High Underground Booking with the intent to put on the best heavy 4/20 celebration around!

Our main event occurs annually mid-April (generally the Saturday closest to 4/20) in Baltimore, operating since 2017, the festival has operated under other monikers but permanently switched to Grim Reefer Fest in 2019.

Our goal is to celebrate the amazing and diverse heavy bands from around the east coast (and beyond) and roll up into one amazing heavy hitting day of live music. We truly believe that this region has the best underground music scene around and we're proud to do everything we can to support it!
