It's probably best to describe this 2005 release as a hybrid mixture of electronic club/dance grooves (including trip-hop, chillout, and ambient), pop-jazz, and world music. Of course, world music is a very broad, far-reaching term - and on Pyramid in Your Backyard, it means everything from Indian, Arabic, and Middle Eastern music to Brazilian samba.
This is a largely instrumental CD, but if Praful (who plays guitar, keyboards, and the Indian bansuri flute in addition to his tenor and soprano sax) is essentially an instrumentalist, he is an instrumentalist who isn't afraid to feature the occasional vocalist.
