The band's second album is due to be released on 12 May on Anti.
Anti have so far only listed a purple version which is apparently limited to 1000

However Norman have up a red translucent version limited to 300

Norman don't usually do exclusives, however I haven't been able to find this version listed anywhere else at the moment.
