The return of the king: Elvis DVDs primed to coincide with 50th anniversary of 1954 debut.(DVD)

When it comes to selling DVDs in large volumes, heritage acts and live performances consistently dominate the sales racks. Add in the additional lustre of a truly legendary performance and you have discs to die for.

It is easy to imagine, then, that the two Elvis Presley discs being offered by BMG will set the pace through the summer.

To mark 50 years since Elvis's That's All Right was recorded at Sun Studios, Memphis, on July 5 1954, BMG is scheduling a series of celebratory releases, including a single release of that landmark track, a 19-song set of Sun-era numbers titled Elvis At Sun and an album collecting some of the greatest all-time rock'n'roll standards, titled Kings Of Rock 'N' Roll.

But possibly the most exciting of all the releases will be two DVD titles which have been put together in the US in direct collaboration with the Graceland estate.

Elvis: Aloha From Hawaii is a deluxe two-disc package incorporating more than four hours of material from 1973's NBC TV special, which was broadcast from Honolulu in Hawaii and relayed around Europe and the world, as well as in the US, where it drew 51% of the viewing audience.

Besides complete versions of the January 12 and 14 concerts, the discs will include a host of additional never-before-seen footage; of Elvis arriving for the shows, a post-concert session, photographs and other footage.

That package alone would be likely to keep Elvis fans smiling through the summer, but it doesn't stop there. Arguably the piece de resistance is the release, also on July 5, of the three-disc version of Presley's 1968 Comeback Special.
