For those well-versed in Indian classical styles, Western improvisation and geometric progressions in music, the album "Metaraga" is a fascinating melding of math and music, eastern and western music. For those who don't recognize all of the influences within this album, it is an interesting blend of sounds and tempos, with two violins (mathematician-violinist Purnaprajna Bangere and David Balakrishnan from Turtle Island String Quartet), bass (Jeff Harshbarger) and tabla drum (Amit Kavthekar).
The livelier tracks are the first two, especially "Syzygy". Track 6, "Alabama," is a cover of John Coltrane's "Alabama," featuring clarinet (Robert Walzel). The last two songs of the album are traditional ragas. These are slower, contemplative pieces that fit in cooler, acoustic portions of sets.
