Olly Murs + Delseasa

Poppy British singer-songwriter Olly Murs made his name via The X-Factor in 2009, and in the succeeding years has released two hit albums and published his autobiography—by age 28! In fairness, songs like "Heart Skips a Beat" are catchy enough (and that track features fellow U.K. hit makers Rizzle Kicks, also in town this week), and Murs recently released his third album, Right Place Right Time.
