That other thread was stupid. This thread is stupid too... but hopefully less stupid. I probably already did this one too but I'm pretty much devoid of ideas just now.

In this the advanced version, we shall start with a band and you will tell us how they are connected with another band.

For instance,

Iggy Pop

then someone posts:

David Bowie. Bowie played keyboards for/produced Iggy's Raw Power.

then someone posts:

TV on the Radio. Bowie sang on track 3 of Return to Cookie Mountain. And so on. It doesn't matter how you connect band to band. Can be someone who played on the album, produced whatever.

Get it? OK, go!

Pixies
