The Sour Truth is a collaboration between English musicians Stanley Belton as Black Market Karma and Peter Kember as Sonic Boom.

The release was supported by a minimalist absence-of-presence music video layered with different film styles and analogue textures.

The collaboration came about when Peter Kember found the track on Stanley Belton's Black Market Karma social media profile.

[2] The music contains cycling Lo-fi guitars, stacked tremolos, shimmering vocals and sugary winding synths, laced with lyrics expressing the pain of cognitive dissonance after loving a version of someone that turned out to be a facade.

It has been likened towards artists such as Spacemen 3, Panda Bear, Jesus & Mary Chain, Brian Jonestown Massacre, Spiritualized and MGMT.
