Yes Acoustic: Guaranteed No Hiss is the video release of an acoustic concert by the progressive rock group Yes recorded live on 26 January 2004, and broadcast live to movie theaters around the United States following the première of the documentary Yesspeak. After the film was played in theaters, cameras cut live to a small studio in California with an audience of about 100 people, where Yes performed the first complete acoustic concert of their career.[1][2]
