Blush Response is a synth pop band based in Los Angeles, California, USA.

They are best known as the band that split from Brandon Flowers in 2001 when he declined to relocate to Los Angeles with them. Flowers did not sing for the band - instead he played the keyboard. Flowers went on to be one of the founding members of The Killers, when he noticed a classified ad for them in a local newspaper.

Blush Response is on the Various Artist collection Electricity - An Electropop Sampler on Ninthwave Records under the name Subversion with a song called "The Victim." It is not known if Flowers was a member at the time of this recording.

Blush Response is also the title of a track on the Blade Runner soundtrack, which was composed by Vangelis. In the film, suspected replicants were examined by a Voight-Kampff machine. Blush response was one of the criteria by which humans could be discerned from replicants. It should be noted that the Vangelis track in question sounds nothing at all like the music of the band Blush Response.
