There are two known bands named Heir 1) A late 1960s Psychedelic Funk Soul & Rock band from USA 2) A Hardcore punk from Auburn, CA. 1) Heir released just one album on Capitol Records in 1969 titled Pollution, With its freaky mash up off rock jazz funk blues and soul there likened to Blood Sweat & Tears. With both male and female vocals and a psychedelic spin on most of the seven songs on the album, It should interest most collectors of soul and psych alike. After line up changes including adding Dobie Gray on vocals they re-emerge under the name Pollution, This band cut a further 2 albums "1971's S/T Pollution" and "1972's Pollution II"
