Justin Timberlake Releases 'Mirrors,' New Eight-Minute Song: Listen

Justin Timberlake performs onstage during the 55th Annual GRAMMY Awards on February 10, 2013 in Los Angeles, California.

Epic track follows JT's comeback performance at the Grammy Awards.

Justin Timberlake has released another new song from his highly anticipated third album, capping off a night that also included a performance at the 55th Annual Grammy Awards as well as a comeback set at the Palladium in Los Angeles. "Mirrors," an eight-minute track produced by Timbaland, is now available on iTunes.

Unlike the compact new single "Suit & Tie," which radiates old-school swagger (thanks in part to a Jay-Z guest verse), "Mirrors" is a vulnerable epic that recalls the aching tone and transformative structure of "Futuresex/LoveSounds" highlight "What Goes Around..." At the 5:35 mark, the expansive strings and pounding rhythm evaporates as Timberlake strips away all pretense to croon to his soulmate. "Now you're the inspiration of this precious song, and I just wanna see your face light up, since you put me on/So now I say goodbye to the old me, it's already gone/And I can't wait wait wait wait wait to get you home," Timberlake sings above piano flourishes and a scrambled vocal sample.

"Mirrors" was not trotted out for Timberlake's much-ballyhooed return to the Grammy stage: instead, JT performed a big-band version of "Suit & Tie," with Jay-Z jumping onstage for his rap verse, and then debuted the rhythmic "Pusher Love Girl" on his lonesome. "Pusher Love Girl" is the lead track on "The 20/20 Experience," due out Mar. 19 on RCA Records, while "Mirror" is track No. 9 on the 10-song standard edition.

Watch Justin Timberlake's Grammy Performance

Timberlake's performance at the Grammys and at the Palladium was preceded by a one-off show last Saturday (Feb. 2) in New Orleans, where he debuted new music during Super Bowl weekend. During the Grammys telecast, Timberlake appeared in a Target commercial where it was revealed that the Target edition of "The 20/20 Experience" would include two additional tracks.

Before his Grammys performance, Timberlake told Ryan Seacrest that "We're definitely gonna go on tour" during E!'s pre-show coverage of the awards ceremony. The pop singer was mum about details of an upcoming trek, which would be the first since his run supporting 2006's "FutureSex/Lovesounds."
