For those wondering about Tull's legacy, there's a whole lot of astonishing music to familiarise yourself with. Start with Stand Up (1969), their only UK Number One album, before moving to their most famous album, Aqualung (1971), which features the extremely popular title track and the anthemic Locomotive breath.
A US Number One album you could try is Thick As A Brick. Fans also adore the underrated Minstrel In The Gallery (1975). You can also taste a bit of their folk music (Songs From The Wood), sample the electronic rock (A) and finish with the hard rocking Crest Of A Knave (1987), which beat Metallica to win a Grammy for Best Hard Rock/Metal Performance.
Then, when you're a Tull convert, check the entire discography.
And yes, go catch them live!
Jethro Tull play in Mumbai on January 29, in Bangalore on February 3 and in Delhi on February 5.
