Perhaps you prefer your jazz with a heavier, djenty bottom end? Do you maybe wish math rock were more melodic? This week’s WTFITF features Echonest, a post-jazz djent math rock mashup that seems singularly focused on exploring the tonal and rhythmic potential of the 8 string guitar in a stripped down trio. Drums(Mike Lamardo), bass (Keith Lewis) and an Warren Sharp on 8 string manage a wide dynamic range with surprisingly rich layers for just a trio. Don’t expect to hear vocals on this live recording- you can tell from the precision that these are technicians and purists, and they don’t need a frontman to shred a roomful of  faces into a pile of smiles.
