A three-band concert brings together Mastodon, Deafheaven, and Alcest for a night of heavy, genre-spanning music at Franklin Music Hall in Philadelphia. The program pairs Mastodon’s riff-driven metal with Deafheaven’s blackgaze fusion and Alcest’s atmospheric black metal, offering a diverse live experience. Franklin Music Hall, housed in a converted factory, stands as a key Philadelphia venue for large-scale rock and metal acts.
