This weekend there are two biggy acts coming to town that I recommend if you can find a way to get in (and there is always A WAY in Amsterdam):

Modest Mouse. Need I say more? Melkweg, Saturday. Huzzah!

Patti Smith. Yes.. the great one. Another sold out challenge for ya.
Paradiso, Sunday.

Oh and wear as few bits of clothing as possible, it has got to be almost 90 degrees F out there ( just short of 30 C).
