If you’ve always wanted to own a piece of Britpop history, your chance might be coming sooner than you think! Rare recordings by Oasis and the Stone Roses will be up for auction on February 21 and 22. Omega Auctions in Stockport, England are offering a number of tantalizing demo recordings and other rarities from the two Manchester bands.

Items up for auction later this month include:

– Oasis’ first demo cassette, allegedly recorded in Liverpool in 1991 and 1992, which features Noel Gallagher’s handwritten tracklisting. The nine track tape has an estimated price of £1,000 – £1,500.

– A rare promo cassette of Oasis’ debut, Definitely Maybe, with a value of £200 – £300.

-The original poster for Oasis’ 2000 single, ‘Go Let It Out,’ signed by all the band members except Liam Gallagher, valued at £800 – £1,000.

– A Stone Roses demo featuring the unreleased track, ‘Sun Still Shines,’ and rough takes of ‘(Song For My) Sugar Spun Sister,’ ‘Going Down,’ and ‘Elephant Stone.’ The demo has been valued at £2,000 – £3,000.

– A rare cassette of the Stone Roses’ 1989 self-titled LP, £200 – £300.

Omega Auctions has sold Oasis and Stone Roses memorabilia in the past. A signed platinum disc for the 1995 Oasis hit, ‘Roll With It,’ was sold for £4,100, and John Squire’s painting, ‘Don’t Stop,’ netted £6,000.

The auctions will be held on Friday, February 21 and Saturday, February 22. Both auctions will begin at 10:30 a.m. Omega Auctions will allow bidders to view the items on Thursday, February 20 from 11:00 a.m. to 6 p.m. and before the first auction on February 21 from 9:00 a.m. to 10:30 a.m. The catalogue for both shows was made available on February 7.
