Summer Jam, Hot 97’s annual cavalcade of stars from the world of hip-hop and R&B, went down yesterday at the Meadowlands with sets from Drake, Nicki Minaj, and Ludacris. Oh, and Usher, who only had to fly in from a Justin Bieber–featuring Paris performance earlier in the day to make his appearance. Elsewhere, Governors Island was rocked by Yeasayer, the Brooklyn Flea by Camera Obscura, and traditional non-noteworthy venues by Delorean, Psychedelic Furs, Stars, and Broken Bells. See it all in our weekend-concert slideshow.
