Solo singer AleXa has returned with her 2nd single album, 'ReviveR'. 

According to AleXa's ZB Label, the singer's latest title track "Xtra" is "a nostalgic throwback to bubblegum pop from the 2000s, with groovy horns conveying a funky vibe reminiscent of past summer hits like Ariana Grande’s 'Problem' or Christina Aguilera’s 'Ain’t No Other Man'. Armed with a banging beat, intoxicating bounce and addictive hooks, the track’s confident attitude exemplifies the spunk and authenticity AleXa embodies as a performer."

AleXa's "Xtra" MV also co-stars KARD's B.M, bringing a crew of his own for a fiery dance battle. 

“Xtra” is the prelude to the origin storyline in the AleXa Universe and is a colorful celebration of 2000s pop culture. This chapter, set years before AleXa is first seen escaping evil masterminds ZB Corp in “Bomb,” showcases AleXa’s life as a teenager before being turned into an A.I.

Meanwhile, AleXa's 2nd single album 'ReviveR' also contains the b-side track "Obsession".
