Nadja is a duo of Aidan Baker (guitars/vocals/piano/woodwinds/drums) and Leah Buckareff (bass/vocals). Nadja began in 2003 as a solo project for Baker to explore the heavier/noisier side of his experimental/ambient music performed mainly on the electric guitar. In 2005 Buckareff joined in order to make the project more than just a studio endeavour and to allow Nadja to perform live.

The duo combines soundscape, electronics and atmospheric vocals with slow, epic riffs and dirge-like percussion, creating a slowly moving grand wall of music that has been described as drone, ambient-doom, and shoegazer-metal. Aidan noted that they prefer to call their style of music "ambient metal" or "ambient doom", though he's fond of the term "dreamsludge" as well.
