Re: Deep Purple versus Jethro Tull!
Tull.....been a fan since This Was. A band that progressed (there's that word...) nicely over the years. Great combination of blues, rock, folk, etc.
Stand Up, Benefit, and Aqualung are simply must have lp's for rock fans...though many prog heads like the later ones like TAAB and Passion Play.
Never really much of a fan of DP though I do like the self titled 3rd and In Rock..and there are some great hard rock tracks on Fireball and Machine head.
