I have my doubts that it would be that early in the morning. People are just crawling out of bed at that time, especially since the music isn't starting again until after midnight tonight.
The show at the Campito Bar is advertised for 11pm. That means he probably won't start there until 1am. My guess is that he is playing in Cabarete around 9 or 10 PM, but don't quote me on this, I am just speculating.
In any case, I'll be going to both venues. He's my favourite Bachatero!
