This is a great track that I keep on coming back to. Everybody's talking about tango rhythms and a tango sound, though I really can't hear much of either, just an old-school rock sound with some unusual instrumentation and rythmic motifs. The arrangement goes a lot of places while retaining an original sound, and I think the inclusion of the pitched percussion is an important component in this. I like ilp0's newer arrangements too (the production in partcular is much better), but having been listening to this for over a year now I don't think it's been topped.
