Though Baton Rouge’s prolific Thou began a decade ago as one of metal’s sludgiest sludge bands, the five-piece is not to be pigeonholed. They can pull off stunning displays of ambition, with plenty of songs extending beyond 10 minutes in length. That’s what made the band’s brutal, atmospheric, and critically acclaimed 2014 opus, Heathen, so impressive, as frontman Bryan Funck and company integrated acoustic guitar passages and the spectral vocals of Emily McWilliams. While the band have just five proper albums to their name (including a collab LP with Providence duo the Body), that hardly sums up the extent of their discography. They’ve also released a slew of EPs and compilations, not to mention their covers of songs by the likes of Nirvana, Nine Inch Nails, and even the late singer-songwriter Vic Chesnutt. With Cloud Rat, False, Moloch, and Anonymous Choir.
