Long Island, New York’s Dream Theater are the globally celebrated standard bearers for progressive metal in the 21st century. Their ability to deliver tight, melodic, musically sophisticated songs and thematic concept recordings encompassing elements of hook-based hard rock, riff-fueled metal, syncopated prog, and refined lyrics have made them the act others are measured by. Their second album, 1992’s Images and Words, established their sonic signature, while 1994’s Awake and 1999’s Metropolis, Pt. 2: Scenes from a Memory cemented their place in metal’s pantheon. Dream Theater is well known for high-energy concert performances. While they’ve released several 21st century live albums — Live at the Marquee, Live in Japan, and Live Scenes from New York — they remain one of the genre’s most bootlegged bands. For 2016’s The Astonishing, a double-length dystopian sci-fi opera, they were accompanied by the Prague Symphony Orchestra and three choirs. In 2021, the band issued A View from the Top of the World.
