Confusing the band name with a person is forgivable in the case of England’s Jethro Tull. The real man, an farming innovator born in 1674, was a key figure in what is known as the agricultural revolution. Why is this relevant? Because although the band formed by Ian Anderson in 1967 is often planted in the Prog category, this is not entirely accurate. Tull began playing blues rock but soon diversified their sound and style to include progressive and especially UK folk influences. The concept albums "Aqualung" and "Thick As A Brick" are perhaps best known, though later LPs are full of great tunes and brilliant playing. Try Songs From The Wood or the heavier "Crest Of A Knave" (1987). Or test the waters with the excellent "Best Of" compilation.
