What songwriting duo is also known as the Glimmer Twins? Here’s a hint. They’re still performing live together to this day. The answer is… Mick Jagger & Keith Richards. You see this nickname used for mostly producer credits on Rolling Stones LPs in the 70s, but it refers to these two members of the Stones exclusively, no matter what the capacity of their involvement is. Jagger & Richards are as important as other songwriting duos of the same time period, like Lennon & McCartney. With songs like “Satisfaction”, “You Can’t Always Get What You Want” “Sympathy For The Devil” “Brown Sugar” and “Gimme Shelter”, their timeless output will be studied and enjoyed long after they’re gone.
