I'm happy that you decided to stop by and leave a comment about it. I was curious to see what artists that actually come from this style would think. You're right that the electric guitar is not typical for this style of music. I was looking through a bunch of Salsa music to hear if there were any guitar parts, and I couldn't really find any for inspiration. I wanted to combine Salsa with what I'm more familiar with and that is Blues/Rock&Roll. Even the chord progression is more Classical influenced and I wanted to marry the different styles together while keeping it mostly a Salsa piece. For the guitar, we found that it works best if it followed the groove of the bass because the bass plays before the downbeat as it anticipates it. I'm sure you know this as this is typical in Latin music. But that is not so much the case from the background that I come from.
By the way, I've listened to several pieces from your Jazz band on Youtube, and they are a real joy to listen to. I have much respect for your playing and sound. I'm hoping to hear more from you in the future.
