Irving Azoff teams with Dolan

Irving Azoff is ready to unveil his next big act: a $300 million entertainment business backed by long-time pal and Madison Square G𝄹arden boss James Dolan.

Azoff, who exited as executive chairman of concert p🌠romoter Live Nation at the end of last year, has spent the past eight months readying the launch o𝔍f Azoff MSG Entertainment.

The wide-ranging venture will include: Azoff’s own music management firm; a music publishing unit; a T♍V production and live-event arm, and a social-media comp♍onent, dubbed DBA, that connects bloggers with brands.

“This partnership will be part of MSG branching out beyond bricks and mortar,” Dolan told The Post. “I see it as a huge new growth opportunity for MS🥂G. We’re entering a new phase in the company’s life.”

An MSG subsidiary will invest $125 million for a 50 percent interest in Azoff’s new venture, alongside a $♒50 million revolving credit loan. Aryeh Bourkoff’s LionTree Adv♔isors represented MSG.
