The older style of fidling like Denis McGhee etc does sound just as complicated. However, it is working with the accordian that becomes the problem. The style predating the arrival of the accordian is much more in keeping with the Acadian style. The reason that the fiddle sounds so raw is that they tune down to be able to play with the accordian. Alot of the accordians are tuned in "C" so they play in "C" and "G". The fiddle keys are "A" and "D" therefore tune down and away you go.
Listen to dennis mcghee, Hackberry ramblers, Canray fontenot and you will hear the breakdowns etc that are not popular any more.
Good luck it is well worth the effort to dig out the older style. It is basic but they couldn't afford good top quality insruments and the recording equipment was bad.
All the best.
