Early Western farming, spread into Europe, was violent with massacres, in 5000 BCE

Mass graves of massacres from 5300 BCE

The pig was domesticated in West Asia (anatolia) around this time and as it spread into Europe it cross-bred with the wild boar of Europe.... losing almost all the original West Asian genetics.

But the farmers essentially countered the wild bog gene flow:

despite gene flow, the genomes of domestic pigs have strong signatures of selection at loci that affect behavior and morphology. We argue that recurrent selection for domestic traits likely counteracted the homogenizing effect of gene flow from wild boars and created 'islands of domestication' in the genome.

So he traces the music style back to the original human culture - the San Bushmen.

The Basque got agriculture around 5300 BCE.

The Basque did equal term trading with the natives here in the WEstern hemisphere.

the banks of the Saint Lawrence River. A trade language, a pidgin based on Basque and American Indian languages, developed and was used by both American Indians and Europeans. ... I believe that adesquide and ania are words from a Basque-based pidgin spoken by members of several native tribes in eastern Canada.

Mattias Jakobsson from Uppsala University in Sweden analysed the genomes of eight Stone Age human skeletons from El Portalón in Atapuerca, northern Spain.
These individuals lived between 3,500 and 5,500 years ago, after the transition to farming in southwest Europe.
The results show that these early Iberian farmers are the closest ancestors to present-day Basques.

After the initial farmer-hunter mixture was set, the ancestors of the Basques became isolated from surrounding groups - perhaps due to a combination of geography and culture.
"It's hard to speculate, but we've been working with Basque historians and it's clear from the historical record that this area was very difficult to conquer," Prof Jakobsson told BBC News.
This means the Basque area was largely unaffected by subsequent migrations that shaped genetic patterns elsewhere in Europe.
