I was doing some youtubin' and came across a video, which while unfortunately has pretty bad sound quality you get to see the ever elusive Jose "Apache" Rivera in action at a Cajon ceremony (on caja). Nicky Laboy is on cajon as well (mula). I am not familiar with the other players, maybe someone can kindly drop that information. Abi Holiday goes from the cachimbo to get on guataca a couple of minutes into the song and takes the lead singing as gallo.
(We previously had a clip of the video embedded on the page, but opted to remove said clip out of respect to those in attendance at the ceremony).
If you still want to see the clip you can catch it here
