A well-worn topic I know, but, us fans of all things indie have had almost every band we possibly like reform if physically possible.
That said, some have been better than others.
Good: Pixies (initially, that first wave of 2004-05 tour, not so sure about now!)
My Bloody Valentine made the same noise and incredibly retained the same amount of mystique they had in the early 90's.
Bad: Sorry to say, but Pavement. Really uninspiring, dull, phoned most of it in.
Ok.....now your go.
