I don't think My Bloody Valentine is " too old to be my father." My father is in his mid '60s. Now, if you're talking about Kevin Shields... You're still way off.
Most of the bands I listen to are made up of people who are either younger thanI am, or ten-twenty years older (like the band we are all here to "get gay over"). So all in all, I think that's a pretty half-assed insult, and not at all a good point.
But why does that matter? I would probably love a new MBV album no matter what, but am also conscious of the fact that it might not be received well by younger audiences. It would be a shame if the album bombed because some 22 year-old Pitchfork writer said it was dated. My liking it would not stop MBV's record from being fucked, and that's my real concern. I want new generations to continue to get into the band, and modern critics have absolute authority over all of that.
