“You can judge any anime by the weight of its theme music. The best themes feel like an entire movie’s worth of activity condensed into one minute, a concerto of guitars and thumping drums and lyrics that you won’t remember but sound amazing in the moment. Cannon Busters, which recently debuted on Netflix, has a theme song for the ages. The rousing “Showdown” is performed by Marty Grimes and BJRNCK and features slick guitar licks, bubbly synths and a literal backing chorus. It’s imbued with the amount of soul befitting an anime with a mostly Black cast”. – Dylan Green (BET.com)
