"What Doesn't Kill You..." is the tenth and final studio album by American rock band Blue Cheer, released in 2007. The album includes a remake of their own song "Just a Little Bit" from their 1969 album Outsideinside, as well as a cover of the classic blues track "Born Under a Bad Sign."
David Fricke, a noted music critic, praised the album as "a strong studio calling card," highlighting its impact and significance as a final statement from the band.
The album features two different drummers: Joe Hasselvander of Pentagram plays on half of the tracks, while the other half features original drummer Paul Whaley. The title, "What Doesn't Kill You...", references Friedrich Nietzsche's famous aphorism, "What does not kill me makes me stronger," reflecting the band's resilience and enduring spirit.
