George Clinton and Sidney Barnes were well acquainted by the time they arrived in Detroit to work for Wingate and Bratton. 

They had been introduced to each other by George Kerr, prior to working for Raynoma Gordy at Jobete Music, in New York City, in 1962. 

After Jobete, Sidney moved on to Sue Records, then Red Bird Records, as a songwriter and artist. At Red Bird, he recorded some classic songs including "You'll always be in style" and "I hurt on the other side".

George took his group, the Parliaments, to Detroit in '64 and signed with Motown. Being in the shadow of the mighty Temptations, however, nothing came of this venture. 

Clinton and Barnes then teamed at Golden World, joining forces with Mike Terry to form Geo-Si-Mik Productions.

The first mention of Geo-Si-Mik on a Golden World 45, came in July 1966 via Tony Michael's release, "I love the life I live".

One of their best productions was by the Parliaments. It was the classic double-sider  "That was my girl" c/w "Heart trouble". Joe Hunter and Bert Keyes provided the arrangements for those songs.

George and the Parliaments moved on to Revilot in 1967 where they released a number of 45's including the classic "Testify" which reached Pop #20, R&B #3.

It wouldn't be too long before the birth of Parliament and Funkadelic, and a whole new ball game, in P-Funk.
