I've always liked A and Roots to Branches. Each has a unique sound/sound-world among Tull albums ("Batteries Not Included": Tull > Sparks). Never heard Under Wraps (I have it) but if I'm not mistaken it's one of Anderson's?/Barre's? favorite albums, plus it's the last gasp for his voice. Only heard Broadsword once and didn't like it. Maybe I should give late-period Tull albums a shot after I finish with the Stones before starting on McCartney.
How bout that Cup?
