This week’s new releases include brand-new albums from Dinosaur Jr’s J Mascis and Eleventh Dream Day, plus the Pet Shop Boys’ ballet score, Black Francis’ silent-film score, the monster reissue of Primal Scream’s ‘Screamadelica’ and a new edition of Nick Lowe’s ‘Labour of Lust.’

Billed as its ‘only European show of 2011,’ organizers of the U.K.’s Bestival this morning announced The Cure will headline one of the festival’s four nights next September alongside Crystal Castles, the Beach Boys’ Brian Wilson, DJ Shadow and Primal Scream performing its 1991 album ‘Screamadelica.’

Last night, Primal Scream performed the first of two London gigs dedicated to the band’s seminal 1991 house-rock hybrid ‘Screamadelica,’ which will be commemorated in 2011 with a massive 20th anniversary box set and tours early next year of Australia and the group’s native U.K.

Primal Scream will celebrate the 20th anniversary of ‘Screamadelica’ next year with a lavish 4CD/1DVD/2LP box set highlighted by ‘a new cut of the album’ made with occasional collaborator Kevin Shields of My Bloody Valentine.

One of the last C86 acts left standing, Primal Scream next year will perform its 1991 classic ‘Screamadelica’ — the album that saw Bobbie Gillespie and Co. trade their indie-pop sound for house-influenced, druggy dance-rock — in its entirety during a series of live dates in Australia, New Zealand and the U.K.

Primal Scream will perform its 1991 classic Screamadelica— the album that saw the band shed its C86 indie-pop sound in favor of house-influenced, druggy dance-rock — in its entirety for the first time ever Nov. 27 at London’s Olympia.
