Jason Mraz and manager Bill Silva parting company after 18 years

Jason Mraz and his longtime manager, Bill Silva, are going their own ways after 18 years of making beautiful music together.

The parting ends a nearly two-decade partnership for Silva, formerly San Diego’s top concert promoter, and Virginia-born troubadour Mraz, a two-time Grammy Award-winner who lives in Oceanside.

The two met in 1999. Bay Area native Silva had previously overseen management of such San Diego bands as blink-182 and Unwritten Law. After teaming up with Mraz, he played a key role in transforming the then-unknown singer-songwriter into an international music star whose hit songs include “I’m Yours,” “The Remedy” and “I Won’t Give Up.”

The parting between Mraz and Silva is an amicable one.

“It was serendipity and a chance meeting in 1999 that started an incredible 18-year journey,” Silva told Billboard magazine Thursday.

“It has been such a pleasure to work with an artist who walks the talk of generosity, compassion, and bringing joy and healing to the world through his music. We both got to be student and teacher at various times during our years working together. I feel so fulfilled to see the many people around the world who are touched by Jason’s music every day, and to have played a part was very special.”

Beginning today, Mraz will manage his career himself. As of this writing, though, the homepage for the “Management” section of the Bill Silva Entertainment website still lists Mraz as a client and includes his photograph.

Silva will still have plenty to keep him busy. With business partner Andrew Hewitt, he is now in his 27th year of exclusively booking pop-music concerts at the Hollywood Bowl. In 2015, their Andrew Hewitt & Bill Silva Presents company had an annual revenue of $30 million.

The acts Silva and Hewitt have presented at the 18,000-capacity bowl range from Mraz and the Rolling Stones to James Taylor and Queen, whose current lead singer, Adam Lambert, is also a former San Diegan. Upcoming Silva/Hewitt shows at the bowl include Imagine Dragons, Zac Brown Band, Chance the Rapper and Tom Petty & The Heartbreakers, who also perform Sept. 17 at the KAABOO Del Mar festival.

Mraz is now working on music for his next album. In late 2015, he married Christina Carano in Mraz’s Virginia hometown of Mechanicsville.
