Packed show this week on EastCast as we go on an audio tour of the brain to find out what the organ sounds like, plus Guerilla Science tell us about a brain themed feast in a Dalston basement later this month. We hear from the residents of traditional market on Crisp Street in Poplar in the first of a series of podcasts. We also caught up with Mike, the Dalston busker who we spoke to a few months ago when he was threatened with eviction. He's now recorded a mini album so we'll be playing a track from that, as well as other music by bands playing around the East End, like Julia Kent, Lindstron and Context. Listings include St Patrick's Day shenanigans, theatre a sea shanty choir. We've got East London covered.
