House DJ/producer Sebastian Ingrosso collaborates extensively with Steve Angello, the founder of Size Records, under a variety of monikers including Angello & Ingrosso. Along with Angello, Eric Prydz, and Axwell, Ingrosso is a member of the Stockholm-based group Swedish House Mafia. Though he’d labored as a house producer for several years prior, Ingrosso scored his first major hit in 2005 with “Together,” a collaboration with Axwell that was licensed for major-label release. A string of hit collaborations followed in 2007 — “Get Dumb,” billed also to Axwell, Angello, and Laidback Luke; “It’s True,” billed also to Axwell; and “Umbrella,” billed also to Angello — as did an entry in the two-CD Ministry of Sound mix album series Sessions.
