I started looking on the website of Corn Exchange, probably the biggest event venue in Cambridge (http://www.cornex.co.uk/ccm/portal/). For some reason, as you can probably guess from the recordings I've done so far, I really like recording classical music. Therefore, I found International Concert Series very interesting and I sent an e-mail to Corn Exchange asking for possibilities to record one of the concerts. To have enough time both for preparing before the concert, and for processing and producing the album afterwards, I have only 2 options: Bournemouth Symphony Orchestra on 22.01.2009, or Russian State Philharmonic Orchestra on 3.02.2009.
I got very nice reply saying that as long as performers are happy to record the event, the venue will let me do it as well - good start! Today, I sent an e-mail to BSO, and now I am searching for a contact to RSPO. Fingers crossed!
UPDATE:
On this website, I found out who is managing the tour of RSPO in the UK, and e-mailed him as well. Fingers crossed again!
