Andy G's description of the Killer Bees is similar to mine... they served as opening band for many touring reggae shows in Austin, their "home base". There are 3 studio albums I know of - Groovin' (a late 80's release with some nice tracks), All Abuzz (from probably 7 or 8 years ago), and another one that combined some of the tracks from Groovin. Their music was my first exposure to reggae, and although I quickly advanced from their sounds to JA reggae, their live shows will always hold a special place in my heart. The band almost always had a 2 or 3 piece horn section when I saw them play out.
Michael E. Johnson, singer for the group, passed away 2 or 3 years ago due to a heart attack or heart failure. The guitarist, Papa Mali, still plays in various bands around town, although not entirely reggae.
If you want exposure to their music, look for Live in Berlin rather than the other albums.
Charlie Pride's son, Carlton, has a reggae group simply called the Carlton Pride Band. I've never seen them, so I can't attest to their music.
Andy G - do you still live in Houston? I was working downtown Houston last week, and ate dinner at the New Reggae Hut. Good spicy jerk chicken, but a bit short on musical vibes. When I arrived, they had Steel Pulse's live cd playing. After it finished, I asked the bartender to put on some more music, but no Steel Pulse or Bob Marley. She rolled her eyes, started the Steel Pulse cd again, and turned back to watching Lifestyles of the Rich & Famous.
