After the one-two punch of his 2003 releases Blood Sutra and In What Language?, Vijay Iyer continues to push his own playing and his collaborators in compelling ways. Recently signed to Savoy Jazz, the label drops the first in a multi-album deal today. Iyer has a fresh set of original tunes on offer here, opening with dizzying speed and gymnastic aplomb on the aptly christened “Revolutions.”
