Updated: Live audio of "Only When I Walk Away" can be heard below. It's the best available so far, since an official version isn't likely to arrive until the album releases.
Justin Timberlake headlined Saturday's lineup of the iHeartRadio Festival in Las Vegas, and he made sure to throw in some newbies among his hits.
Nestled between favorites like "SexyBack," "Cry Me a River" and "My Love," Timberlake introduced the never-before-heard "True Blood," off his forthcoming The 20/20 Experience: 2 of 2. Although not exactly a standout track at first, the audience seemed to give it a shot.
Following trimmed versions of "Suit & Tie" and "Holy Grail," both minus JAY Z, Timberlake performed "Mirrors" as well as newer singles "Take Back the Night" and "TKO," before launching into another premiere, closing out his set with the incredibly addictive chorus of "Only When I Walk Away," which is sure to be on the lips of many fans in the coming weeks.
2 of 2 arrives on Sept. 30.
Watch his entire performance below. Note: "True Blood" is around the 4:00 mark, "TKO" around 24:00 and "Only When I Walk Away" starts at about the 42:00 mark.
