Music is still the best way to express love, loss, joy, and the manner in which to agitate anatomical parts after putting them in and taking them out. Get ready to shake it all about with today’s GrouponLive deal: for $32, you get two general-admission lawn seats (a $50 value before fees, or up to a $64 value online, including all ticketing fees) to see Def Leppard, with special guest Heart, at Jiffy Lube Live on Sunday, July 31, at 7:30 p.m. Reserved seating is assigned on a first-come, first-served basis upon ticket pickup at will call. In order to sit together, Groupons must be redeemed together.

Generation gaps call an evening-long truce to absorb the electric harmonies and magnetic energy of legendary rock bands Def Leppard and Heart. Def Leppard began its ascent to British hard-rock royalty in 1977, solidifying its reign with the 1987 multiplatinum album Hysteria and its iconic anthems "Love Bites" and "Armageddon It." Its latest tour stokes nostalgia and then pours sugar on it, with library classics giving way to singles such as "Undefeated" from the forthcoming Mirror Ball – Live & More album. Heart frontwomen Ann and Nancy Wilson add to the aural carnival with sisterly harmonics and guitar-wrangling routines developed over more than 30 years onstage. Revelry-inducing '70s hits "Barracuda" and "Crazy on You," along with soul-clutching '80s power ballads "Alone" and "What About Love," embody the decades whence they came while continuing to forcefully knock the socks and toenail polish off rapt concertgoers.
