Chamber jazz with a touch of gypsy jazz, very clean-cut stuff. It's not at the energy level of Django Reinhardt style "hot club" music but has the same elements: perky acoustic guitar, violin, mandolin, etc. Piano & some synths too. An open-air artistic feel that's quite proper but still has a sense of fun -- there's a semi-sarcastic faux-sultriness to 3, for instance, and cartoony fun on 16. Instrumental, FCC clean.
(Full track-by-track is on Zookeeper.)

1- Calm, clean melody. Slowish, over busy triplet guitar. Speeds up by the end.
2- Coolly popping swing, midtempo
3- A complex tango. Mid/fast, fun
4- Spare, playful. A softly fun midtempo one.
5- Some tension. Gets into a strong flow w/some Eastern European flair.
6- Midtempo, slinky. Not quite a tango.
7- Fast and whispery intro, into snappy theme
8- Mid/fast. Tense chase-scene feel.
9- Calm, simple chiming.
10- Perky, quite hot club-like
11- Swirling synth-string drama, piping oboe(?) Slow. Later, a busier gypsy sound with banjo.
12- Tense, sneaky, and quiet. Soundtrack feel. Cool ending, where the piano really builds up.
13- Quite classical feeling. Cute piano exercising, maybe too cute
14- Pattering 9/8, quick and catchy
15- Slowish, with a cutesly classical theme.
16- Playfully sneaky, like mice thieves tiptoeing around.
17- Mid/fast but not busy. A very clean, harp-like sound; you could hear this at an art-gallery opening.
18- Flowing and sweet, quite soundtracky.
