For those who only know Grandaddy from the latest album Sumday: Buy this album.
For those who know Grandaddy from the beautiful The Sophtware Slump: Absolutely buy this album.
For everyone else: Buy this album.
Ok, it's hard to find, I myself managed to buy it through Amazon in America, but it was worth it (by the way, I spent 12 euros...).
So the album has only 7 songs, and it's the first album by Grandaddy (1995), the sound, in my opinion, is not recorded very well, most likely they are also demos, but it’s the content that counts: THERE ARE 7 GREAT SONGS.
I point out my two favorites: Taster and Gentle Spike Resort.
Anyway, if you've never heard Grandaddy before, I recommend the amazing first album: The Sophtware Slump.
