A few weeks back I picked up a promo copy of a compilation CD called "Achili Funk: Gypsy Soul 1969-79" for £1 in the Crouch End Oxfam shop. I am not quite sure what I thought Gypsy Soul was going to be, but it probably wasn't this, which in the main Spanish rumba spiced up with the pop and disco sounds of that period. That isn't a criticism. There are some great Saturday night tunes on the album - these three for a start.
"Pares O Nones" - Los Marismeños
"Gol" - Trigal
"Baila Mi Ritmo" - Los Chunguitos
Also from Spain around that time, here is a group that started with the rumba, added some pop and disco sounds, and then took the rumba out again. It's Baccara!
