Big Sir is the longtime collaboration between singer/composer Lisa Papineau and bassist/composer Juan Alderete (The Mars Volta). Since its inception in the late 90s, Big Sir has explored a vast array of work centered on the fulcrum of electronic and analog beats, Alderete’s fretless bass and Papineau's dynamic voice.
Alderete and Papineau first met in the band Pet. Throughout their relationship the two musicians have also continued their collaborations with other artists. Papineau has lent her vocals to a spectrum of projects such as the last two Air albums (10,000 Khertz, Talkie Walkie), M83’s Before the Dawn Heals Us, and soundtracks for the films Watchmen and Super.
Alderete has played in Grammy award winning The Mars Volta since 2003 as well as playing bass with rap legend Kool Keith’s Dr. Octagon and the Omar Rodriguez Lopez Group. In 1999, he formed the project Vato Negro and released the album Bumpers on drum& bass label N2O.
Their latest release consists basically on remixes and new versions of the songs from their previous album "Before Gardens, After Gardens", which was released in 2012.
