Journey was formed in San Francisco in 1973, composed of former members of Santana and Frumious Bandersnatch. The band has gone through several phases; its strongest commercial success occurred between 1978 and 1987, after which it temporarily disbanded. During that period, the band released a series of hit songs, including 1981’s “Don’t Stop Believin’,” which in 2009 became the top-selling track in iTunes history amongst songs not released in the 21st century. Its parent studio album, Escape, the band’s eighth and most successful, reached No. 1 on the Billboard 200 and yielded another of their most popular singles, “Open Arms.” Its 1983 follow-up album, Frontiers, was almost as successful in the United States, reaching No. 2 and spawning several successful singles. Journey enjoyed a successful reunion in the mid-1990s and later regrouped with a series of lead singers. Sales have resulted in two gold albums, eight multi-platinum albums, and one diamond album (including seven consecutive multi-platinum albums between 1978 and 1987). They have had eighteen Top 40 singles in the US (the second most without a Billboard Hot 100 number one single behind Electric Light Orchestra with 20), six of which reached the Top 10 of the U.S. charts and two of which reached No. 1 on other Billboard charts. Originally a progressive rock band, Journey was described by AllMusic as having cemented a reputation as “one of America’s most beloved (and sometimes hated) commercial rock/pop bands” by 1978, when they redefined their sound by embracing pop arrangements on their fourth album, Infinity.
