Journey is an American rock band that 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. During that period, the band released a series of hit songs, including "Don't Stop Believin'" (1981), which in 2009 became the top-selling track in iTunes history among songs not released in the 21st century.[2][3] 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; it broadened the band's appeal in the United Kingdom, where it reached No. 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 U.S. (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 US chart and two of which reached No. 1 on other Billboard charts, and a No. 6 hit on the UK Singles Chart in "Don't Stop Believin'". In 2005, "Don't Stop Believin'" reached No. 3 on iTunes downloads. 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" after 1978, when they redefined their sound by embracing pop arrangements on their fourth album, Infinity.[4] According to the Recording Industry Association of America, Journey has sold 48 million albums in the U.S., making them the 25th best-selling band. Their worldwide sales have reached close to 90 million records, making them one of the world's best-selling bands of all time.[5][6] A 2005 USA Today opinion poll named Journey the fifth-best American rock band in history.[7][8] Their songs have become arena rock staples and are still played on rock radio stations across the world. Journey ranks No. 96 on VH1's 100 Greatest Artists of All Time.
