1) Non-“beliebers,” bear witness. According to Billboard, Justin Bieber counts over 10 billion total video views on Vevo—the first artist to do so. He was also the youngest solo male act to reach number one on the Billboard 200 since Stevie Wonder. Bieber not only sings and dances but also plays guitar and piano. The man’s undeniably a phenomenon. Bieber, who is from Stratford, Ontario, began as just one of countless child singers on YouTube. Then R&B singer Usher became his mentor. An almost-overnight teen heartthrob, Bieber has since pivoted his career toward a more mature sound. Bieber’s won two Grammy Awards and is nominated for another one this year for best R&B Performance for “Peaches.” After his concert here we may see him the next night in Los Angeles for the Grammy Awards Ceremony. Also on his Justice World Tour are Jaden, Eddie Benjamin, and ¿Téo?. 7:30 p.m. PPG Paints Arena, 1001 Fifth Ave., Uptown. (C.M., R.H.)
2) Area native Donnie Iris, aka King Cool, is performing at the Roxian Theatre tonight with his band, The Cruisers. Sure to be on the set list are top favorites including “Ah Leah” and “Love Is Like a Rock.” Iris was once a member of the Pittsburgh group The Jaggerz in the early ’70s who had a monster hit with the “The Rapper,” which reached no. 2 on the Billboard Hot 100 chart. The Thistle Brothers open. 8 p.m. 420 Chartiers Ave., McKees Rocks.
