Josh Groban is an American singer-songwriter known for his powerful voice that oscillates between baritone and tenor. An enthusiast singer from a very young age, he was 16 years old when he attended the Interlochen Arts Camp, a training camp for budding artists where he discovered a real vocation for the stage. Aware of his exceptional vocal abilities, his vocal coach introduced him the following year to producer David Foster. In his early days, he worked as an understudy in several major American shows, a job that led him to sing with Celine Dion at the 1999 Grammy Awards. In parallel to his career as a young singer, Josh Groban continued his studies and entered a prestigious university, but he gave up everything to devote himself to music. That same year, he signed a contract with Warner Brothers under the tutelage of his producer. The 2000s proved to be very productive for him and he released a first eponymous album which mainly contained classically influenced tracks. It was a successful opus that very quickly went double platinum. From then on, he was noticed by the big names in the music world and performed duets with Lara Fabian and Sarah Brightman. He also performed in charity shows, singing with Elton John and Stevie Wonder. In 2003, his second album "Closer" was a hit and reached the top of the charts thanks to the single "You raise me up". Since then, the singer has not stopped counting his hits and has been touring extensively. He also made a foray into television and cinema, appearing in the series "Glee" and "Les Experts" as well as in the film "Crazy, Stupid, Love" alongside Ryan Gosling and Emma Stone.
