Time Life is commemorating two milestone industry anniversaries with the release of two special DVD sets.

Arriving Aug. 31, "The Best of Soul Train" three-DVD set celebrates the 40th anniversary of the iconic dance series. It will be followed Sept. 28 by a second three-DVD set, "The 25th Anniversary Rock and Roll Hall of Fame Concerts."

Hitting retail for the first time, the "Soul Train" set covers eight hours and features 50 exclusive performances by the Jackson Five, Marvin Gaye, Aretha Franklin, Sly & the Family Stone, Barry White and Stevie Wonder, among others.

These performances - many of which haven't been seen in over 30 years - were culled from the show's archives, dating back to 1970. Rounding out the package are more than three hours of bonus material, including exclusive interviews with "Soul Train" founder/host Don Cornelius, Smokey Robinson and others.

"'The Best of Soul Train'" offers a rare, insider's view of the golden era of soul," says Cornelius, "marking a classic time and place which can never be duplicated."

Filmed over two nights last October at New York City's Madison Square Garden, "The 25th Anniversary Rock and Roll Hall of Fame Concerts" encompasses the four-hour, Emmy-nominated special that aired on HBO.

The 51 performances feature sets by such legends as Paul Simon, U2, Bruce Springsteen and Crosby, Stills & Nash, joined onstage by a lineup of special guests ranging from Jerry Lee Lewis and Bonnie Raitt to Mick Jagger, B.B. King and Fergie. Also included: an additional 16 bonus performances not seen on HBO and a collector's edition of Rolling Stone featuring behind-the-scenes stories.

A Blu-ray version of the package will be available exclusively at Best Buy for the first 30 days of release. The DVD anniversary set joins the previous Time Life/Rock and Roll Hall of Fame multi-platinum DVD release, "The Rock and Roll Hall of Fame Live."

"These concerts capture the spirit of the Rock and Roll Hall of Fame, which recognizes the outstanding and inspiring artists who have made an impact with their music," says Jann Wenner, Hall co-founder and publisher of Rolling Stone magazine.
