For me, that album is My Bloody Valentine's 'Loveless'
Possibly the leading album in shoegaze, yet I just can't get into it. I hope I will one day, because people go insane for it. I do like the track 'When You Sleep' in passing though. I guess it's just a /mu/core album I just can't get into, which is strange, considering I can get into others, like Neutral Milk Hotel's 'In the Aeroplane Over the Sea', and Radiohead's 'Kid A' although I haven't listened to anything else by Radiohead yet.
But I don't know. How about you?
