The combined deals, estimated at around $200 million total, marks an acceleration of a run on hip-hop assets.
The deal, which includes the superstar's interests in his publishing and recorded music catalog, is likely to close in the next few days.
The music investment firm shows global ambitions by acquiring the catalog through a new U.S. subsidiary.
At an investor presentation in London, founder Merck Mercuriadis said the company’s current share price “fundamentally undervalues the company.”
The deal includes the entirety of the iconic singer-guitarist's work, dating back to the late 1960s.
The deal includes Azalea's master and publishing share of her biggest hits "Fancy," "Problem," and "Black Widow."
The sale includes Nilsson's publishing catalog as well as artist and writer revenue streams of hits like "Without You," "Coconut" and "Everybody's Talkin'".
New venture will allow investors to buy fractional shares in iconic artists' song rights.
In a deal that includes both rights to Prima's masters and publishing, Reservoir now holds shares of classics like "Sing, Sing, Sing" and "Pennies from Heaven."
The purchase, estimated at $325 million, includes royalty streams for songs by artists like Tech N9ne, George Jones and Trey Songz, among others.
