The Lot Six formed in summer 1999 in Boston with the lineup of vocalist Dave Vicini (ex-member of Vagrant recording artists Boxer), guitarists Will Kerr and Julian Cassanetti, bassist Dan Burke, and drummer Aaron Sinclair. By January 2001, Espo Records released a debut 7", followed by The Code Mode EP in March 2001. The first full-length, Gwylo, finally came in June 2003 and in October was followed by Animals, a supplementary album that was recorded during the same sessions.
