I was thinking about bands that were really popular/successful during two distinctly different phases ..... and how that phenomenon will probably never happen again. For example- Bands like the Doobie Brothers (original & Michael McDonald version), Yes (classic vs. Rabin era) , Chicago and Genesis (70s vs 80s), and even Van Halen or Fleetwood Mac. These bands were successful, and then made major changes to their lineup and sound, and then were really successful again! I suppose this question will only apply to bands/collective acts... since solo artists tend to change styles, but essentially remain themselves Does the modern landscape of popular music still seem conducive to this anymore? I am admittedly out of the loop. Imagine Dragons might've had two different but successful phases that I am simply unaware of. Has Destiny's Child dropped any new hits without Beyonce? I honestly don't know. Do fans of younger pop acts still have the debate about which distinct phase is better/more legit ?? Or is this phenomenon truly obsolete now?
