This month's programme looks at water and how it fits into the lives of people in Hackney. Author and psycho-geographer Iain Sinclair follows the route of Hackney Brook, a subterranean ghost river which runs from Highbury to Hackney Wick.  Then to Clissold Leisure Centre for Wet Sounds, a new music event in which electro-acoustic composers Francisco Lopez, Stefano Tedesco, Tom Haines and Leafcutter John serenade their floating audience through speakers above and below the water. Moving on to London Fields Lido, architectural historian Simon Inglis explains how swimming pools in Hackney have their roots in the wash houses set up by 19th-century philanthropists in the battle against cholera.  And we hear from the people who work and live on Hackney's waterways today

Francesca Panetta meets the dogs and dogwalkers of London Fields, London Review of Breakfasts editor Malcolm Eggs goes in search of the Magic 9 ingredients at Stoke Newington Farmers Market, and we visit the Dalston Mill, modelled on environmental artist Agnes Denes’s New York work of 1982, and providing a rural retreat on some disused railway line in Dalston.  Plus a report from the Drawing Room's recent season of events celebrating the work of experimental English composer Cornelius Cardew, whose graphic score for Treatise will be on display from November

Francesca Panetta joins John Hopkins - the Olympic Delivery Authority’s Project Sponsor for Parklands and Public Realm - for a tour of the site.  This will be London's first major park since Victorian times, and is intended as a contemporary take on the great British landscape and garden tradition.  The 100 hectare parkland will accomodate an 80,000 capacity stadium, a velodrome, a Zaha Hadid-designed aquatic centre and a media centre for 20,000 journalists.  How sustainable is the development and what will be its legacy for Hackney?

Recorded at London Fields between 04:00 and 04:30 on Thursday 21st May. London Fields East Side from 00:00 to 03:32, Lansdown Drive (crows) from 03:32 to 04:10. Edits in the recording are indicated by tape generated sounds at 02:27 and 03:32

Buzzing, maddening, chaotic, dirty, dangerous and fun is how locals describe this section of the A10 between Old Street and Dalston Junction.  Hackney poet Shane Solanki has written us a song all about the Kingsland Road, starting a bit further north, up in Stamford Hill.  We meet some of the stall holders at Kingsland Waste street market to find out what drags them out of bed even on the bleakest and rainiest Saturday mornings.  Then it’s down to Crooked Billet Yard to meet Oliver Bulleid of Cox Bulleid Architects for a tour of their Shoreditch Prototype House - a model for low energy living in dense urban environments.  To end, photographer Briony Campbell on her current project documenting the street’s nightlife - she takes us to meet the proprietors of Abel’s Social Club, Passing Clouds, Stoke Newington International Airport, and Visions Video Bar
