Long before he was an internet star for pranks, Rick Astley had a legitimate pop career. Blending soul and R&B with dance pop made him a superstar in the late ’80s, but he kept going as the luster of fame went away in the early ’90s. “Cry for Help” might not have reached the pop culture stratosphere like “Together Forever” or “Never Gonna Give You Up,” but he had legs with his material. Strangely, we can thank the internet for bringing him out of retirement 10 years ago to perform the hits and record new material. You’ll hear some songs from last year’s 50, but his earliest material is what brings the people in. Rickrolling may have given him a new shot at life, but this show is a chance to appreciate what this guy has been doing for almost 30 years.
