Xcel Energy Center added to the '80s music nostalgia cavalcade Tuesday by announcing concerts with revitalized boy band New Kids on the Block and retiring bad boys Mötley Crüe.

NKOTB's Main Event Tour will arrive May 20 and feature two classic R&B/hip-hop acts for openers, Nelly and the surviving members of TLC. Tickets go on sale Jan. 31 at 10 a.m. through Ticketmaster and the arena box office for $29.50-$91.50.

The Crüe will return to Xcel Energy Center on Aug. 5 on what it's calling the "last leg" of its final tour. Tickets go on sale Friday at 10 a.m. for $20-$125, same price range as the band's other final show there in November. Rock and Roll Hall of Famer Alice Cooper will once again open.
