On a personal note, there's no voice I'd rather hear sing me to sleep than Lisa Hannigan's. It's angelic. And in case you couldn't tell from the previous statement, I have a massive crush on her! Just watch the video... you'll see why. She's adorable!
Here's Lisa Hannigan performing "I Don't Know".
Currently, Lisa Hannigan is working on her next album in Ireland. Until then, check out her website. Or if you just can't wait for the new album, I'd suggest buying Sea Sew to tide you over!
