Justin Timberlake and Paul McCartney debuted new tracks from their forthcoming albums at the iHeartRadio festival in Las Vegas on Saturday night.

Timberlake performed new songs 'True Blood' and 'Only When I Walk Away' from The 20/20 Experience - 2 of 2 during his headline slot. The 'Mirrors' singer pulled out his slickest dance moves for 'True Blood', which with its grooving bassline and dark, sexy lyrics made it obvious it was inspired by the TV show of the same name. 'Only When I Walk Away' was a departure from Timberlake's usual gland of glacial R&B, with its funky guitars and overall distinctly 'rockier' edge.

Meanwhile, music legend Paul McCartney also chose the festival to debut two tracks from his new album, called, um, New. 'Everybody Out There' and 'Save Us' were both high octane and rousing, and were promising previews of the singer's first album in six years.
