Whereas Rush's first two releases, their self-titled debut and Fly By Night, helped create a buzz among hard rock fans worldwide, the more progressive third release, Caress of Steel, confused many of their supporters. The band knew it was now or never with their fourth release, and they delivered just in time - 1976's 2112 proved to be their much sought-after commercial breakthrough and remains one of their most popular albums. Instead of choosing between prog rock or heavy rock, both styles are merged together to create an interesting and original approach. The whole entire first side is comprised of the classic title track, which paints a chilling picture of a future world where technology is in control (Peart's lyrics for the piece being influenced by Ayn Rand). Comprised of seven "sections," the track proved that the trio was fast becoming rock's most accomplished instrumentalists. The second side contains shorter selections, such as the Middle Eastern-flavored "A Passage to Bangkok" and the album-closing rocker "Something for Nothing." 2112 is widely considered by Rush fans as their first true "classic" album, the first in a string of similarly high-quality albums.
