Audiences of 12 will be sent to walk the streets of Aberystwyth
An innovative theatre production will involve the audience walking the streets of Aberystwyth.
Armed with iPods and headsets, a dozen theatregoers will trace the journeys of members of a local choir to their rehearsal through the town.
The Outdoors experience will take place every Tuesday night for a year.
It is the brainchild of a German avant-garde theatre group, National Theatre of Wales and the Aberystwyth-based Heartsong choir.
The 25-strong choir has been meeting to sing together every Tuesday for more than 12 years and their repertoire is entirely a cappella.
Its secretary, Carolyn Wacher, said: "Every Tuesday evening during term time audiences of 12 will be given an iPod and earphones, and sent to walk the streets of Aberystwyth.
"Through those iPods, they will see and hear the stories of Heartsong choir members along their journeys.
"There will be 12 different stories from locals that lead them in different paths through the town's narrow streets and seafront.
The audience will join the choir at the town's St David's club
"They will be finally reunited in a wonderful celebration of the power of choral singing at the St David's Club in the middle of Aberystwyth."
National Theatre Wales commissioned Berlin-based reality theatre-makers Rimini Protokoll to make Outdoors its first UK commission.
Rimini Protokoll's latest productions include Call Cutta in a Box, a one-to-one telephone performance that takes place live from a call centre in India, and 100 per cent Berlin, a living arrangement of statistics for 100 citizens on a revolving stage.
Outdoors is National Theatre of Wales' 11th of 13 productions in its launch year.
Its first show, A Good Night In The Valleys, opened in March 2010 at the Blackwood Miners' Institute.
Since then, it has produced shows in a range of locations, from Swansea's old library, Cardiff's New Theatre, Prestatyn's seafront and Sennybridge military range.
National Theatre Wales' artistic director, John McGrath, said: "Rimini Protokoll has done a lot of interesting work with people who are not professional actors.
"We were interested in exploring why people come together to form a choir to sing for a couple of hours a week."
The first performance will take place on Friday 25 February 2011 and then every Tuesday from 1 March 2011.
Tickets are available from Aberystwyth Arts Centre.
