SALT LAKE CITY, Utah — The piano and the bass line were loud enough to hear through the grey-metal door of Northwestern's locker room, because these days, the Wildcats travel with a concert-grade speaker that required its own cleared-luggage tag from Vivint Arena security. The speaker sits nearest the locker of fifth-year senior Sanjay Lumpkin, and Sanjay the de-facto deejay chose Dr. Dre and Snoop Dogg's "Still D.R.E." as the first song on the playlist following the first NCAA tournament win, in the first NCAA tournament trip in Northwestern history—a 68-66 victory over Vanderbilt in an 8–9 seed game on Thursday afternoon.
