Green Day will release some demo recordings to mark Record Store Day 2014.

A post on the Green Day Facebook page alerted fans that, “We are releasing 18 demos, including an unreleased track, from the Uno, Dos and Tres sessions, exclusively for @recordstoreday. It will come out on colored ‪#ývinyl‬, ‪#ýCD‬ and even ‪#ýcassette‬”.

Details of the release are yet-to-be announced and it is also unsure at this stage if the release will be US only or worldwide.

Record Store Day Australia will take place on Easter Saturday.

Green Day are currently in Australia as headline act for Soundwave and played in Sydney and Brisbane last weekend. They also played a secret show in a Sydney pub last week, with fans only finding out about the show a few hours before showtime via Billie Joe Armstrong’s Twitter account.
