Theresa Anderson is new to me, and she is just the kind of music I like. Check out her website for some gorgeous cruisey music, the sort you play late at night when you are chillaxing or best of all when you are driving somewhere a fair distance away and you can sing really loud in the car (see also Natalie Merchant). Anyway I really like this, have a wee listen and maybe you will too!
One thing I love is that on the website you get a lovely big chunk of song. Off to iTunes to see if they have her there. Listen to Innan Du Gar on the website. Here she is doing Oh Mary.
