Take one Back Street Boy and one New Kid On The Block and together you get Nick & Knight, a collaboration between  Nick Carter and Jordan Knight. With a brand-new Nick & Knight album, they're on tour and will hit the Mercury Ballroom on September 17. The album, which features songs written by committees of noted writers, has done well enough to peak at No. 24 on the U.S. Chart so far. Of course, these two still have fans, most of whom at headed into their thirties, who'll come out to see them, no doubt. The whole shebang is one professionally engineered, produced and staged event, so it'll be a thouroughly current pop show that should appeal  to those fans. The critics? No so much. Tickets are $45 + $13 fee.
