Ahh... It is so easy to look south to Miami-Dade and come away as bandits with these "genre" lists. While it is true that there always seems to be a larger pool from which to pick from down there, the current state of affairs in South Florida's music has made the actual pin-pointing slightly more difficult with many bands nowadays sharing members across county lines.
Back in the '60s and '70s, things were a little clearer, and Broward and Palm Beach counties had some serious homegrown talent. Some of these outfits were one-hit or regional wonders and many, thankfully, managed to record for posterity. Many didn't. There are a handful of compilation discs out there and online conservationists who have kept some of that music alive.
As always, this is not an all-inclusive listing, but rather a demonstrative grouping of some of the best talent these counties enjoyed in the '60s.
