With My Eternal Winter, former underground mixtape master Black Panther provides the rare producer's album that actually features a thematic focal point. And true to its title, this effort is a dark one. Whether working with songstress Maya Azucena or rhymer MF Grimm, Black Panther inspires his guests to face their inner demons head-on. Amid the apt presence of a lot of overcast boom-bap, this producer proves to have a respectable sonic range-especially when he throws a curve ball on the melancholy downtempo title track featuring sultry-toned vocalist Meredith Dimenna. Yet even in all its darkness, this disc is no downer.
