The July 5th Album: The July 5th Album is the second compilation album by American pop group The 5th Dimension, released in 1970 by Soul City.  It is composed primarily of album tracks from amongst the group's four albums of original material for Soul City Records, many of which were B-sides to charting singles.  It also includes one A-side single: the group's cover of The Mamas & the Papas hit "Go Where You Wanna Go".  The song was originally intended to be the Mamas & the Papas first single but was replaced with the now-iconic "California Dreamin'".  Choosing that single, and seeing it become successful, became something of a mixed blessing for The 5th Dimension, as they were frequently referred to in the media as "The Black Mamas & the Papas", a label the group sought to escape while creating their own unique identity.
