The stadium-filling band that inspired a million karaoke nights was built on genres that display both grunt and grandeur. Journey's first two albums riffed on the blues-rock fusion of The Jimi Hendrix Experience. By the '80s they adopted the skyscraping dynamics and vocal range of Boston, while their masterful power balladry echoed the cavernous sound and big emotions of Nazareth and Procol Harum.
