Journey is an American rock band that formed in San Francisco in 1973. At that time it was composed of former members of Santana, namely guitarist Neal Schon, who has remained with the band since its inception, and keyboardist Gregg Rolie, who served as primary lead vocalist for the band's first three albums, and Frumious Bandersnatch, most notably bassist Ross Valory, who was with the band until 1985 and since 1995. In 1978, Steve Perry joined to serve as lead vocalist, and in 1980 Jonathan Cain replaced Rolie as keyboardist, and has remained a constant member since. The band's strongest commercial success occurred between 1978 and 1987 at which time Perry departed. During Perry's tenure, the band released a series of hit songs, including "Don't Stop Believin'", which in 2009 became the top-selling track in iTunes history among songs not released in the 21st century. Its parent studio album, Escape (1981), the band's seventh and most successful, reached No. 1 on the Billboard 200 in 1981 and yielded two their other most popular singles, "Open Arms" and "Who's Crying Now". The 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 have since regrouped twice; first with Steve Augeri from 1998-2006, then with Arnel Pineda from 2007 to the present. Sales have resulted in twenty-five gold and platinum albums, in addition to the fifteen-time platinum RIAA Diamond Certified, 1988's Greatest Hits album. They have had nineteen 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" by 1978, when they redefined their sound by embracing pop arrangements on their fourth album, Infinity. 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 over 80 million records globally, making them one of the world's best-selling bands of all time. A 2005 USA Today opinion poll named Journey the fifth-best U.S. rock band in history. 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. Journey was inducted into the Rock and Roll Hall of Fame with the class of 2017. Inductees included Perry, Schon, Rolie, Valory, Cain, and drummers Aynsley Dunbar and Steve Smith.
