Slightly Stoopid will bring their annual 4/20 celebration to Morrison, CO’s Red Rocks in 2013. Dubbed Slightly Stoopid’s 420 Hot Box, the April 20 show will also feature rap icons Cypress Hill and reggae group Tribal Seeds. After Colorado’s voters gave a resounding “Yes” to their state’s Amendment 64 to legalize marijuana this past November, Slightly Stoopid decided to thank area fans by returning to the venue, which they have sold-out on four separate occasions.

Before 4/20, Slightly Stoopid will swing through smaller clubs on their Top of the World tour. The band will kick off their run at Albuquerque, NM’s Sunshine Theater on January 9, and move throughout the Southwest and West Coast as well as Canada. Members of Slightly Stoopid recently joined Karl Denson’s Tiny Universe during their Beastie Boys tribute.
