Big Sean did a solid 50-minute set, featuring his top hits. I wish he would have done more off his first album, but that just speaks to the number of good songs he has/has been featured on.
Lupe did an hour-plus long set, and was strong as well. I am a bigger fan of Big Sean than Lupe, but Lupe definitely kept me entertained and into his show.
As far as the venue goes, the Palladium has good access, and despite a pretty full crowd, is incredibly roomy. Short lines for bathrooms and bars are always nice!
