Journey is an American rock band formed in 1973 in San Francisco by former members of Santana. 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'", the top-selling catalog track in iTunes history. Its parent studio album, Escape, the band's eighth and most successful, reached #1 on the Billboard 200 and yielded another of their most popular singles, "Open Arms". Its 1983 follow-up, Frontiers, was almost as successful in the United States, reaching #2 and spawning several successful singles; it broadened the band's appeal in the United Kingdom, where it reached #6 on the UK Albums Chart. 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, six of which reached the Top 10 of the US Billboard Hot 100 chart and two of which reached #1 on other Billboard charts, and a #6 hit on the UK Singles Chart in "Don't Stop Believin'". Originally a progressive rock band, Journey were 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 traditional pop arrangements on their fourth album, Infinity. According to the Recording Industry Association of America, Journey has sold 47 million albums in the US, making them the 28th best selling band. Their worldwide sales have reached over 80┬ámillion albums. A 2005 USA Today opinion poll named Journey the fifth best American rock band in history. Their songs have become arena rock staples and are still played on rock radio stations across the world.
