At 20, Shawn Mendes is relatively young to be considered a musical veteran. But considering he landed his first major record deal at the age of 14, he’s not necessarily a newbie. The Canadian singer first entered the musical pop culture consciousness as the product of a highly technologically savvy approach to music dissemination: on the video-sharing app Vine, doing covers of pop hits. A sensation there, he soon built a career by growing and nurturing a fan base that clamored for his music — including his own — and his teen-idol good looks. His first album, 2013’s “Handwritten,” was certified platinum during its first week out in the market and produced one of his earliest hits, “Stitches.” He’s since release two more albums (2016’s “Illuminate” and last year’s “Shawn Mendes”) and has headlined tours around the globe. On Monday, he brings his sold-out Shawn Mendes: The Tour to Pechanga Arena San Diego, with fellow Canadian Alessia Cara.
Shawn Mendes: 7:30 p.m. Monday, July 8. Pechanga Arena San Diego, 3500 Sports Arena Blvd., Midway District. Sold out, but tickets with a side view of the stage are available. (619) 224-4171. axs.com
