Aqualung
by Jethro Tull
I'd never listened to the entire album even though I used to own it and am a full album listener typically. It was always the title track that would get the most play, then everyone mentioning the flute. Having not heard the track in a long time, it was a nice revisit and was rocking out. I liked giving it a more mature ear than when I was a teenager/college kid and picking out the pieces differently. Hell, I didn't even know what prog was back then, but am very familiar and love listening to this with that new knowledge now at 47.
