It doesn’t seem like it, but it’s been 20 years since Oasis released their massive debut album Definitely Maybe. To celebrate that milestone, Big Brother Recordings is releasing special editions of Oasis’ first three albums in chronological order, starting with Definitely Maybe May 20.

Definitely Maybe was released in August 1994 and sold more than 5 million copies worldwide. The re-release features remastered tracks. Deluxe and super deluxe versions feature B-sides, previously unreleased live recordings and liner notes from rock critic Neil McCormick.

The band is celebrating the anniversary in other ways, too. For Record Store Day on April 19, a special edition 12-inch LP of Oasis’ debut single Supersonic will be released. A cassette of the band’s original demo is available as well. 

Big Brother will release the band’s followup albums, 1995’s (What’s the Story) Morning Glory and 1997’s Be Here Now later this year. 

More information is available on the band’s website.
