The last disk that had this kind of impact on me (listening to at least 2wice a day (after purchase no less, i downloaded some 'preview' songs early...) was Neutral Milk Hotel's Aeroplane CD.
Simply put- it's elegant, beautifully-crafted, experimental indie pop that makes you think, dream, and be appreciative of having the sense of sound. Like music and collage lyrics out of some surreal diary, these songs overlap and spill forth in such a way (no one song is decipherable from the entirety of the whole disk) that you listen to the whole 76 minutes in total bliss & wonder. Quay Cur, Mason City, Blueberry Boat, Inspector Blancheflower, all are magnificient and diverse.
They have been compared to Belle & Sebastian, White Stripes, Velvet Underground, Capt. Beefheart, Beach Boys, etc.- but they are a little of all of that and their own thing all at once. One other parallel I can draw is to The Microphones epic CD- The Glow Pt. 2- but this album would be that one, albeit more blippy and on Zoloft- happy & melancholic, simultaneously.
Not a particularly even college-radio friendly series of songs, this is a challenging & special disk that deserves a wider audience.
