Yes—Paradise is the better pick today if you want a confirmed band set:

• Paradise Bar & Grill — Island Ripples, 2:30–5:30 PM today, Sunday, August 23
  21 Via De Luna Dr., Pensacola Beach
  Their official event listing confirms the time. It’s waterfront on the Sound side behind the Paradise Inn—good food-and-music choice, and easiergoing than the Boardwalk.

• Sandshaker Lounge — I found a listing for Brandon Giles, 4:00–8:00 PM on a Sunday, but I could not confirm that it is specifically today, August 23, from a current Sandshaker calendar. I’d treat it as a possible option rather than drive over solely for it.

So: go Paradise for the sure thing; Bamboo Willie’s has Thin ICE 3:00–7:00 PM if you prefer Quietwater/Boardwalk.

👉 Are you looking for a laid-back afternoon set or someplace that will still have music and energy after dinner?
