LOS ANGELES (AP) — Usher is teaching a class on how he does what he does so well. Usher has released a series of videos through the online teaching site MasterClass.com that gives viewers instruction on captivating an audience, building a brand and other aspects of being an entertainer. Usher says it’s not like anyone who watches his videos will be an overnight success, because any success earned that way will not last. Usher says part of being a master is trial and error and the tenacity to keep going. Sixteen video classes cost $90.
