Avicii ...what is he? musician, Dj, record producer? "beat chef"? Maybe all of these. At any rate he's had a big year, despite health problems that forced the cancellation of several performances earlier this year. His album "True" hit the top 10 in more than ten countries. It features an eclectic assortment of collaborators, ranging from members of Incubus, to funk producer Nile Rodgers, to bluegrass musician Dan Tyminski, from Allison Krauss & Union Station. The hit single "Wake Me Up" has been viewed nearly 404 million times on Youtube.  Avicii (Tim Bergling) has rented a house in the Hollywood Hills, and is hard at work on a new release. He's reportedly working on more than 70 songs. Rolling Stone reports, the guest list for this one includes another diverse group of collaborators, including Jon Bon Jovi, Coldplay's Chris Martin, and Wyclef Jean. What will this one turn out to be? My curiosity is piqued.
