Portishead: PNYC Live (Polygram, £16.99)
This limited edition boxed set captures the Bristol trip-hoppers at their legendary concert in New York's Roseland Ballroom in 1997, and comes complete with booklet and bonus short film with musical mix by DJ Andy Smith.
Grease 20th Anniversary Edition (Paramount £10.99)
Oh, go on, you know you want to. Digitally re-mastered for the 1990s, this kitsch classic is still enormous fun, and even the naff bits (and there are many) are hugely entertaining. This anniversary edition features retrospective interviews with John Travolta (Danny), Olivia Newton-John (Sandy), Stockard Channing (Rizzo), Jeff Conaway (Kenickie) and other cast members.
