Strathmore has a capacity of around 800 more people than the 930 Club (I found out after doing a quick internet search). With tickets around $55, that is over $40,000 more money.
I had a feeling that Strathmore wouldn't be the best place to see Pixies (I figured driving a few hours round-trip would be worth it for the experience of seeing them in a rock club, and am glad I did).
Anyways, Slowdive!
