Saw a ton of soul and R&B groups growing up, and one thing I always disliked was seeing the band when they don't sound anything like the songs on their records. People age, pass away, voices go, the energy isn't the same, etc. So I'm a bit leery about acts that have been off the radar for a while, since it's much more about the music than the experience for me.

Rappers don't have the same problem of losing their singing voice.
