Many of these artists were veteran session musicians who took their cues from jazz, funk and R&B, funneling those styles into a new strain of slick, assiduously crafted pop-rock.Although these artists scored numerous hits during their heyday, many struggled to survive in the age of MTV. “The ‘video killed the radio star’ thing, it was just absolutely true in my case,” Cross laments in the trailer, while McDonald adds: “I expected to be totally forgotten by the end of the ‘80s.”These artists’ critical and commercial fortunes took a turn in the 21st century, when a 2005 web series called Yacht Rock led to a widespread reappraisal of the genre. While there’s a light ribbing inherent in the “yacht rock” designation, the genre’s biggest stars and songs are beloved by millions, and they remain the soundtrack to many fans’ lives.Top 100 Classic Rock ArtistsClick through to find out how they stack up, as we count down the Top 100 classic rock artists.Gallery Credit: UCR Staff
