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 the late 1970s, solidifying its reign with the 1987 hit 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 Mirrorball live album. Heart frontwomen Ann and Nancy Wilson add to the aural carnival with sisterly harmonics and guitar-wrangling routines developed from 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.
