Blue Lambency Downward is the third studio album by Kayo Dot, released on Hydra Head Records in May 2008. After much of the group left to pursue outside projects, the only members who remained were frontman Toby Driver and violinist and long-time collaborator Mia Matsumiya. The two began recording the album in early 2007 using a revolving door of contributing musicians. The album is heavily influenced by chamber and orchestral music and jazz, and features an abundance of woodwinds. It is widely considered to be Kayo Dot's least heavy album to date.
