In celebration of the 30th anniversary of Green Day’s iconic album 'Dookie', Los Angeles art studio Brain has launched a unique line of lo-fi song formats. Fans can purchase one-off versions like a doorbell chime and a wax cylinder, along with a Teddy Ruxpin doll that sings 'Chump'. The website Dookie Demastered also features a chance to win a $49 wireless doorbell playing 'Longview' and an 8-bit version of 'Welcome to Paradise' on a GameBoy cartridge. Sample snippets are available for nostalgic listening, perfect for annoying coworkers.
