 Defeated Sanity is a German technical death metal band from Dachsbach, Bavaria, that was formed in 1994, originally as a side project of guitarist Wolfgang Teske and his son, drummer Lille Gruber. Gruber is the only original remaining member left in the band, following the departure of Teske in July 2008. The other members are Christian Kühn (guitar), and Jacob Schmidt (bass guitar). For almost a year the band was looking for a new vocalist, due to Jens Staschel leaving the band shortly before Teske; Staschel's replacement, A.J. Magana from Disgorge, was announced in June 2009.
