Wandering in from the Americana column (see page 113) comes Alison Krauss And Union Station Live. The first disc of the double-disc package features the bluegrass favourites in concert, while the second has interviews, behind-the-scenes footage and home videos. From similar territory comes The Three Pickers , a country-folk-bluegrass variant on the operatic template. Earl Scruggs, Doc Watson and Ricky Skaggs all do their thang individually before they unite for a back porch-style picking session. Almost Elvis is an uproarious account of the world of Presley impersonators, of whom there are allegedly 350,000 in the world. It’s amusing, but by the time you get to the extras you’ve seen enough. Prog rock lives on in Supertramp?The Story So Far , which tells their history via interviews, memories and highlights of a 1983 world tour. Recorded last year, Fairport Convention 35th Anniversary Concert finds the folk-rock pioneers creaking a bit. But it’s good to hear the likes of “Matty Groves” and “Meet On The Ledge” again. Springsteen, Costello, Jackson Browne and Bonnie Raitt all guest on Roy Orbison Greatest Hits . But it’s the Big O and that astonishing voice that still holds the attention on a dozen performances of different vintage. Compilation DVDs are usually spotty affairs, and The Singer And The Song is no exception. The ’60s/’70s German TV show Beat Club is once again the source for 22 performances that range from the dull (Kiki Dee, David Essex) to the memorable (Ray Charles, Van Morrison). Maximum R&B is the order of the night on Southside Johnny & The Asbury Jukes?Live At The Opera House . Storming performances of all the hits such as “I Wanna Go Home” and “This Time It’s For Real” are supported by interviews and other bonus material.
