I wanted to post something Irish today as I have just spent the day in Dublin.
These guys have come into a little prominence after Glen Hansard, the lead singer, starred in a Once a couple of years ago.  I really liked them when I was in my late teens and early twenties, seeing them live quite a few times.

The reason they first piqued my interest was that I saw Glen Hansard when he was supporting Bob Dylan and I walked into the show halfway into his set while he was covering Astral Weeks which is an obscure song from my favourite album of all time and I instantly knew I had to investigate him further.
