Vinyl LP pressing. In the Groove is the eighth studio album by Marvin Gaye, originally released in 1968. It was the first solo studio album Gaye released in two years, in which during that interim, the singer had emerged as a successful duet partner with female R&B singers such as Kim Weston and Tammi Terrell. In the Groove was reissued and retitled as I Heard It Through the Grapevine after the unexpected success of Gaye's recording of the same name, which had been released as a single from the original album.
