o, ya wanna see Jethro Tull in concert? Can’t. The group is taking a long break from touring. Perhaps, permanently, if you believe lead vocalist and flautist Ian Anderson. But you can see the man who has been Tull’s guitarist for 43 years as Martin Barre and his band perform the classic music from the Jethro Tull catalogue. And of course you’ll hear Barre’s unforgettable guitar solo on “Aqualung,” which pops up on all kinds of “greatest guitar solos” lists.
