BBC Virtual Session Files
The BBC has this great site called The Virtual Session. It provides you with written music (in sets) and recordings of session players so that you can get a feel for how it would be to play along at an Irish session. It's a stripped down version of what Comhaltas does with their great set of Foinn books and CDs.
Anyway, being kind of anal, I recorded the music as MP3s and made PDFs of the sheet music so that I could play along without being tied to my computer. Since I have them, I'm passing them on to y'all.
