Hats off to Cafe Oto for a very impressive intiative, working with Songkick Detour. They write:

Thanks to Songkick’s new Detour initiative we were able to confirm a concert with saxophonist Colin Stetson at Cafe OTO for 28 October 2013.

Colin had got 50 odd pledges on Detour, and amazingly the show had almost sold out just hours after going on sale this morning. Luckily we’ve been able to secure a second date the day before on the 27 October 2013 so hopefully there will now be a few less disappointed punters!

Songkick Detour is a three-stage process: (1) Interested audience menbers pledge to buy tickets for the artists they want to see, and decide how much to pay. Songkick Detour don’t take payment until the concert is confirmed. (2) SD then work with potential promoters to make the concert happen.  (3) If the concert is confirmed, the ticket price is set and SD charges the audience members, up to a maximum of the final ticket price even if more was pledged.
