(sorry, no links. I'm on my phone.)

1. Eggs and Sausage - Tom Waits, from Nighthawks at the Diner

2. Some Place - Nick Waterhouse, or really, the whole album. (Sexy, hot music too. Guaranteed for some close dancing if you're into the people.

3. Sigur Ros. Full stop. In the many occasions I've done this, it's never failed. Alternatively, my favorite musician is J. Tillman. I put on a lot of his music on for a lot of reasons, but here, I'd go for Crosswinds, from A Year in the Kingdom. This is probably my more honest answer, but I don't share his music often, unless I truly have a deep, deep connection with the person. (There's a compliment for you, hubski.)

4. Bach's final piece: Die Kunst der Fuge. His music was extremely... Mathematical. Baroque music in general was. With a fair understanding of music and math, at someppoint it clicks to you. You can hear parts and know what comes next. Bach was absolutely the highest genius of this. He wrote his name into songs, for example. One of the activities he was known for in his day was having fugue competitions. Bach and another person at two harpsichords face each other. The person plays a segment and stops at a random point. Bach carries on. He never missed a note and always added to thepiece dramat ically. Anyway, his last piece was based around that idea; many songs built around one small fragment. It becomes increasingly complex, in predictable ways. You'reaware of where iit'sgoing. It's all clicking in your head. It nears its summit and... Ends. He died before he could finish it. His music was so rooted in those logical structures though, it's possible for someone to finish it how he intended (and some have). Something about that feeling though, where it comes together, it happensin all of Bach's music with me, but that one specifically, having sudden clarity of directiondoes wonders for your mind. I always listen to it while working, purely for the logical mindset it puts me in.
