Nothing to fight about ..here - at all...
Subject is near & dear to my heart & ears ... as well as many more on this site
That's why I suggested lookin' @ some Youtube channels - It's like a musical journey ...day in day out ..
I like using sites like - LastFM ..to find similair artists
for years I'd only listen to Roots & Dub ... only in the past couple have I grown to enjoy Ska & Rock Steady more & more
Guess I'm gettin' older & more mellow

I'll take a look for the David Katz book ...thanks
