yeah.. you are brave enough to provide an audio sample..

you are obviously quite good
but we [me & mrs] suggest you choose something else to promote yourself..

UK already has enough home grown competition
in the 'intelligent and quirky' singer songwriter market..

but being from the US could still work positively
and open doors for you..

just dont have over-realistic expectations

come here on your first trip to make friends and contacts..
enjoy a 'working holiday'
get a real view of what goes on here..

then make more personaly informed plans for your 2nd trip back here..

take care and have fun

ps.. contact US indie folk/alt country artists like Handsome Family
and their lable & touring mates for friendly constructive advice
on what to expect from UK gigging..

and make sure you have a good night off in Bristol and Cardiff
