There were the eight shows at Barclay's in 2012, where he brought out Big Daddy Kane, Memphis Bleek and Beyoncé; for New Year’s, he did a show with Coldplay. And, of course, he and Justin Timberlake had a couple of back-to-back nights at Yankee Stadium this summer, echoing what he and Eminem had done in 2010. For the Watch the Throne tour, he and Kanye sold out New Jersey's IZOD Center twice, and then MSG, and then MSG again. Plus the two charity balls at Carnegie Hall, an All Points West performance in the mud, a September 11th benefit, a Summer Jam, the three he did with Mary J Blige, and that's not even counting the time he repeated "Picasso Baby" for six hours straight. (There may be more shows - that's just off the top of my head.)
All of which is to say: with Jay Z doing two nights in Brooklyn this weekend, there are those who think they’ve seen it before.
