Well, Wallonia turned out to be very nice indeed, with unexpectedly good weather to go with the expectedly good food and beer. I would particularly recommend a visit to scenic Dinant if you are in the area.
I didn't pick up much Belgian music because CDs are rather pricy there, with most new ones being €18-20 or more. But some scouring of the discount racks and second-hand shops of Namur unearthed a couple of bargains.
One of these was a best of TC Matic, one of Belgium's leading post-punk-funk ensembles. They were active between 1980 and 1986 and had very limited commercial success at the time, with only their debut single "Oh La La La" bothering the Belgian charts at all. The band developed a bit of a reputation in other parts of Europe though, and hung out with the likes of PiL and Simple Minds, and I think their better stuff has stood the test of time pretty well.
"Putain Putain" - TC Matic
"Middle Class And Blue Eyes" - TC Matic
Apart from the scenery, the other thing that the town of Dinant is best know for is being the birthplace of one Adolphe Sax. You can visit his childhood home and admire the many giant saxophone sculptures that adorn the town. In tribute to Mr Sax, here is the thing that on its own justified his life's work.
