Saw them twice in the 70s but they lost me after Heavy Horses. Aqualung is their high point album with Thick As A Brick and Passion Play veering off to into a self imposed obscurity. Other good albums are Minstrel in the Gallery, War Child and Heavy Horses before they had more personal changes and went in a direction I didn’t care to follow.
Back when they use to tour with Zeppelin they were known for heavy drinking and partying. Maybe that has now affected Ian Anderson's voice... mind you Plant's vocal have changed as well and most likely from age.
