Primus and Mastodon

Alternative, Metal, Rock

Led by the Zappa-like Les Claypool, Primus were among the most lovably strange bands of the ’90s, blending metal, funk, and post-punk. Last year, they revitalized their quirkiness with The Desaturating Seven, inspired by Italian children’s book The Rainbow Goblins, of all things. Mastodon, though similarly crucial to the evolution and shape of metal, have exemplified the genre’s cornerstones of power, proggy ambition, and speed. Last year, they released their Emperor of Sand LP and Cold Dark Place EP.
