BMG Rights Management is once again expanding its international reach, with the acquisition of the catalog of U.S. publisher Adage IV.

The catalog contains songs recorded by artists including John Mayer, Ray Charles, Rob Thomas, Joni Mitchell, Faith Hill, Elvis Presley, Frankie Lymon, Joe Cocker, The Beach Boys and Frankie Valli & The Four Seasons.

Included among the acquired music rights are well-known tracks such as "Stay," "Let's Go Get Stoned," "Little Darling," "I Don't Need No Doctor," "Breathe" and "Why Do Fools Fall In Love."

"This is an important step in our acquisition strategy to get attractive catalogs," Hartwig Masuch, CEO of BMG Rights Management, tells Billboard.biz.

Masuch went on to say that "more acquisitions" would take place in the near future, "which will underline this philosophy." According to Masuch, the Adage IV catalog contains more than 500 titles.

No details were provided about the price of the deal.

"Working with BMG Rights provides an opportunity to participate in the future of music publishing," said Herb Jordan, founder and CEO of the Adage Group -- a Los Angeles-based company specializing in the acquisition of intellectual property rights -- in a statement.

"The Adage Group looks forward to contributing to the growth and success of BMG Rights," he continued.

BMG Rights Management -- a joint venture between international media company Bertelsmann and private equity firm KKR - was founded in 2008 by Masuch, former BMG Music Publishing Germany CEO, and now represents the rights to more than 100,000 songs and recordings.

This latest deal from the company follows the recent acquisition of several French publishers, including Music Addict Publishing catalog and Editions PRK Music (Billboard.biz, Apr. 27). Earlier this year, BMG Rights Management also acquired Cherry Lane Music Publishing - the company's biggest acquisition in its brief history (Billboard.biz, Mar. 26).
