Katherine informed me of your post, We have a monthly session in Leicestershire which is not a million miles away, please check out our website, www.salmagundi.me.uk
We call it an Acoustic Pickin' Session and we currently have a mix of styles but I am trying to raise awareness to bluegrass music in the area so any pickers are more than welcome.
Probably closer to home, The Toy Hearts play virtually every Sunday night at the Roadhouse in Stirchley. They are an excellent band to go and see. I have known Stewart for about 30 years from when I lived in Brum and he is very approachable friendly guy and may well be able to help you in your quest for a session.
Dan and I are planning to get over ourselves in the not too distant future so who knows you might see us there.
