Procol Harum, a British rock group known for their art rock and prog rock sound, achieved success with their trademark melancholic vocals and lush melodies. Lead singer and pianist Gary Brooker, along with primary lyricist Keith Reid, crafted songs like "A Whiter Shade of Pale" and "A Salty Dog" that pondered the unpredictability of fate. The band was one of the first to experiment with large-scale orchestration, performing on-stage with a full symphony ensemble. Over the years, they released albums like A Salty Dog and Procol Harum Live: In Concert with the Edmonton Symphony Orchestra, showcasing their skill and passion for music.

Procol Harum's journey began with instrumentalist Gary Brooker forming the group at a young age, eventually finding success with hits like "A Whiter Shade of Pale." The band underwent various lineup changes but continued to release albums that resonated with audiences in both the UK and the US. Despite disbanding in the late '70s, Procol Harum reunited multiple times over the years, releasing new music and embarking on tours. Their legacy lives on through their innovative approach to rock music and the enduring impact of their classic songs.
