Just bought The National's Alligator and realised I now had every LP they'd released and it got me wondering how many bands I had done this with. Off the top of my head I believe this is also the case for modest mouse, death cab, elbow, 65dos and interpol though there maybe more*.

What bands have anyone else picked up the all albums by?

*I've discounted artists with three albums or less as it could get silly.
