Did Denver band The Drood take its name from Charles Dickens’s final, unfinished novel, The Mystery of Edwin Drood? We may never know, and that suits this enigmatic crew’s sound — space rock with a dark, dreamy edge — just fine. The group’s mix of fluid psychedelia and sludgy prog/krautrock calls to mind the Legendary Pink Dots, Hawkwind, Saint Vitus and the Melvins. The bandmembers perform in masks, bringing a sense of theatricality to their shows and giving a sort of “Alice Cooper of gloom pop” impression. The Drood will share the stage at Globe Hall this Friday, April 15, with Church Fire and Cloudspell. This rare performance by these Denver weirdos may make you feel as though you’re sitting in with a forgotten cult in its musical sanctum sanctorum.
