A&M/Octone Records signed and developed worldwide multi-platinum superstars Maroon 5, platinum modern rap-rockers Hollywood Undead, platinum modern-rock act Flyleaf, and internationally acclaimed hip-hop artist K'naan. A full-service artist development label, A&M/Octone operated music publishing, merchandising and touring rights companies – in addition to specializing in recorded music. After six successful years of operation, in September 2013, Octone initiated its buy/sell rights in the joint venture, resulting in Universal Music Group purchasing Octone Records' 50% interest in A&M/Octone Records.
Previously in 2000, Diener founded Octone Records, an independent label distributed through BMG, while simultaneously serving as Senior Vice President of A&R/Marketing for Clive Davis & the RCA Music Group, now a division of Sony Music Entertainment. As part of that relationship, Diener negotiated an exclusive joint venture with Sony Music that gave Octone the ability to upstream successful acts in partnership with the RCA Music Group for further international marketing and promotion. Also, while at RCA, Diener signed and developed platinum singer-songwriter Gavin DeGraw.
Diener was also well known in the music industry for its entrepreneurial private-equity financing model. Upon Octone's original launch, he capitalized the label with $5 million of private equity investment – individual investors drawn from blue-chip companies BlackRock, The Blackstone Group, Lazard Freres, Credit Suisse First Boston, MacAndrews & Forbes, Kelso & Company and Soros Fund Management.
Prior to his dual status as CEO/President of Octone Records and Senior Vice President of A&R and Marketing at RCA Music Group, Diener was Vice President of A&R and Marketing at Columbia Records from 1992 to 2000, where he worked with such platinum and developing artists as Aerosmith, Bruce Springsteen, Bob Dylan, Pink Floyd, Johnny Cash, Black Crowes, Clutch, The Jayhawks, Tony Bennett, Roger Waters, Chris Whitley, Jesse Malin, Iron Maiden, Terence Trent D'Arby, and New Kids on the Block, among others.
