Spiral Shadow is the fifth full-length album by American sludge metal band Kylesa.

A metal band to the bone, Kylesa stomp the clichés right out of psych-rock on Spiral Shadow. The Georgia band's new album, their fifth in less than a decade, is the next step in a pretty seamless evolution that's hidden increasingly complex (and catchy!) music behind an attack that still hits with the in-the-red rawness of hardcore.
