Probably my favorite “2000 band”
Picaresque, Crane Wife, The Hazards of Love, The King Is Dead. Beautiful, really interesting music and lyrics on most of their albums.
My story is I took a gamble on Picaresque and Crane Wife but when Hazards Of Love was released, I resisted all contact with it. Their tour would bring them to my city and I wanted the experience of hearing them play it live before I listened to any of it or bought it. I was very patient, my wife and I went to the concert and enjoyed it immensely and then afterwards, I bought the album to relive the concert experience.
I highly recommend any two of the albums I mentioned as a starting point if you have any interest in listening to The Decemberists.
