What I gather from The Black Pine is that they are a group of talented musicians that love to rock out together. They may have side gigs in the music industry and tours and appearances, but when they get together you can be sure that you're going to get some really delicious sonic honey.
Smooth, classic in feel and vibe, and an all around pleasure to listen to: "Waves" is a great morning gem or midday calming tune to hit the play button on.
What you're going to hear is a great vocal with a solid mix between it and the production. It's a smooth listen, catchy and familiar with very beautiful guitar-strumming throughout.
The chorus has a bit of a retro vibe that adds the nostalgic sensation I believe it was meant to have. Just a very solid and pleasurable listen, all around.
