If I were you I woudl start at the very begining and get WESTING BY MUSKET & SEXTANT first,

listen to spiral stairs' and S.M.'s lo-fi noise freakouts, then get Slanted & Enchanted

and rock that shit homie, then go and get Crooked Rain Crooked Rain, which is their first truly "mature"
Pavement album,
and fucking fall in love with it. Then get woweee zoweee
and brighten the corners.....
