The British progressive rock band YES released their eighteenth studio album "The Ladder" in 1999. "The Ladder" contains eleven songs (including the three singles "Homeworld (The Ladder)", "Lightning Strikes" and "If Only You Knew") and mixes influences from Latin American music with the band's progressive rock sound. It was the first album in a long time that was not produced by the band itself, but by an external producer - Bruce Fairbairn, who had previously worked with bands such as the Scorpions, AC/DC and Bon Jovi. "The Ladder" was released in September 1999 and reached number 36 in the UK charts.
