Actually, a broad assemblage of studio musicians, led by bassist James Jamerson Jr. (son of the famous Motown bassist James Jamerson) and guitarist David Williams (4).
The two of them met while playing with The Temptations's road band, and this is when they hatched the idea of Chanson.
They released two albums with such hits as "Don't Hold Back", "I Can Tell" and "Jack De Nimble".
By 1980 the duo was labeless and forced to return to studio session work.
Not that it's a bad thing, in fact their real success is behind the scenes.
Together and seperately they can be heard on countless pop, rock, R&B and disco tracks.
