On my trip to wellington last weekend Johnny (the younger brother of a friend I was staying with) suggested I might want to check out Calexico. I got a hold of 2 of their albums, one is a joint effort with Iron and Wine (who I also really like a lot), and the other is Calexico alone.
If you're into folk guitar type sounds (Iron and Wine, Belle & Sebastian [twee pop â€“ but a similar sound]), Sufjan Stevens etc) I can highly recommend In The Reins. The album Feast of Wire was a more interesting mix, which I'm lead to understand is more core Calexico. Jazz, Afro-Latin, and acoustic guitar blend with beautiful voices to create a masterpiece. I'm quite impressed.
