Strangely enough I wasn't really in to Motown at the time, but I love the early stuff now. One real gem I found on the net...Four Tops, Walk Away Renee, acapella version, absolutely awesome.
Have you seen the film "Northern Soul"? Absolutely awesome. The soundtrack is insanely good, and the whole atmosphere of the Wigan Casino scene seems very close to the second wave of UK rave which blew me away in the late 90's. Different era, different music, exactly the same thrilling vibe, when you're 19 and suddenly discover there's a lot more to going out than getting plastered in pubs.
I actually think like our taste buds change over time, so do other things.. like our ear of music.. I always loved Northern and Motown, but have appreciation now for other things, not just music, I would never have given the time of day too..
