Once in awhile my best friend and I go look at open houses. Of course, we always choose the most expensive ones, because when else do you have the chance to explore a $10-15 million home? One house we were looking at had two rooms in the basement with a window in between. I told my friend it looked a lot like a recording studio, and lo and behold, some days later we discovered we had been wandering around Kirk Hammett's house. It's still possible to find photos of this house online: http://sf.curbed.com/2012/3/9/10389834/metallica-guitarist-kirk-hammetts-old-abode-is-back (There are more photos here.)
