An all grundo rock band that came to the Concert Hall shortly after the discovery of Kredulor! They play on the 25th of every month.
Space... and rock music? We are so totally there, man! Rocking is our specialty. Down with Sloth and all that, yeah. Oh, wait, what's this about a slingshot?
Gruundo were originally called GrĂ¼ndo, but the umlaut was removed when it caused issues with searching on the site.
