Handwritten (2015)Mendes learned to play guitar by watching YouTube tutorial videos at the age of 13 in 2012. Less than a year later he started posting cover videos on the social video app Vine in 2013 and gained millions of views and followers in a few months, becoming well known for his six-second snippets of renditions of many popular songs. By August 2014, he was the third most-followed musician on Vine. Artist manager Andrew Gertler discovered Mendes online in November 2013, bringing him to Island Records in January 2014. He officially signed in May 2014.
