There are at least 5 artist with the moniker XO:

1. XO was created by Canadian singer-songwriter The Weeknd, as an unofficial imprint to release 3 mixtapes in 2011.

2. XO are an American shoegaze/alternative rock band from Atlanta, Georgia. The band consists of twin brothers Jeff (guitar, vocals) and Jacob (bass, vocals) Turner, who also perform in the band Say Anything. Live, the band are joined by guitarist Joe Assef and drummer Parker Case, who also plays drums on some studio tracks. Although the band formed in 2004, a year before the Turners joined Say Anything, the band did not release any material under the moniker until 2008 - a six-track EP entitled Some Day. Their debut album, Heart, was released in February 2014 via Rory Records, an imprint on Equal Vision Records run by Max Bemis of Say Anything.

3. Xavier Osayande - also known as X.O. - is a Nigerian-American rapper from San Diego, California.

4. As bonafide dance music becomes increasingly intermingled with various disparate genres, there are certain producers who tend to stand out in the ever-growing crowd of unclassifiable music. 19-year-old British producer/songwriter XO is definitely one of those producers. The Through The Night EP features a distinct fusion of house, trip-hop, R&B, and electronica. Through The Night's lyrics and melody practically qualify it as a musical aphrodisiac, while Pulling Me Under is deeply relatable on an emotional level. RobLaw and Leo Kalyan are both prime choices as vocalists, contributing an invaluable element of soul and sensation that most electronic tracks tend to lack. The two singles leave little room for categorization and certainly establish XO as a major breakout force in the upcoming year.
