Most of the material on the CD (all of which was written by Medeski, Martin & Woods and John King) has a bluesy and R&B feel. "Miami Gato" does add a Latin flavor with nice light work on the piano. There's a lot of wah-wah guitar on the "Curtis" track. And the sax solo by Briggan Krauss adds R&B to the mix. The party ends with "Queen Bee" which features a repetitive riff heavy on the blues.
"The End of the World Party" CD is full of sound from beginning to end with emphasis on the organ and wah-wah guitar. It almost says that if you let up on the sound, the party will end.
