Dreadnought manages to meld fairly disparate sonic elements into a coherent whole. Inspired by the image and power of capital ships, in the era before aircraft made battleships and their ilk obsolete, Dreadnought (due at the Marquis Theater on Friday, May 3) creates music that, though heavy and dark, has both an atmospheric grandeur and a classical sensibility. Mixing a symphonic palette with crunchy guitar and an almost baroque compositional aesthetic with the feral energy and vocal style of black metal, it's like little else out there, except maybe Mono or Caspian. The band's debut full-length, Lifewoven, is an imaginative exploration outside of standard musical parameters and genres.
