Very cool about the show and your wife.
I haven’t seen the documentary except for the clip of the song 23 Minutes in Brussels that’s posted on YouTube, which apparently is taken from it: http://www.youtube.com/watch?v=81Sv57rbujA
I just discovered Luna about a year ago and they are great. I actually bought Rendezvous when it originally came out, listened to it once, didn’t get it, and then didn’t listen to it again until sometime last year on a whim. For some reason it clicked this time. Since then I’ve gotten a few others — Pup Tent, Penthouse. They’re cool too but Rendezvous is my favorite, probably because it’s the one that first “imprinted” on me.
Every one of their albums are good, each with a different tone. Owning the whole catalog is a good thing. I recommend checking them all out.
