Elvis Costello and The Roots delivered a stirring performance of "I Want You" from their Wise Up Ghost LP live onstage at Brooklyn Bowl on September 16, 2013. Today Okayplayer presents exclusive footage of the sensual blues ballad tinged with gut wrenching passion that mines The Roots' aesthetic from How I Got Over to Undun, bringing their sonic evolution full circle beneath the electricity of colliding guitar solos. Elvis Costello owns this portion of their groundbreaking set, infusing the track with a white hot intensity that hearkens back to J.B. circa "It's A Man's Man's Man's World" and threatens to make the walls melt.
