Our occasional series of anthologies of rare and desirable Group Soul gems kicks off 2016 with a fourth volume of "Soul Harmony" that's sure to be welcomed by all collectors of the genre. As ever, our musical tour of the US takes us to all parts of the country and features tracks that span the mid-60s to mid-70s - the golden era of this type of material. Our featured artists offer a balance of the familiar and the obscure, but all with recordings of the highest quality. There are a few R&B chart hits here but the focus is on quality rather than on rarity. 22 tracks are completely new to Ace or Kent CDs, while nine of those 22 - including rare Stax demos from the Del Rios and the Mad Lads - have never been issued before.
