There's more
Is the audio being recorded by the camera? It sounds like there's some AVC or compression getting in the way a bit, and the Bass was almost non-existent.
Nice performances all round though. Singer slipped a bit in places (but still much better than I could ever do).
Good ears! I was wondering about the bass myself ... but since I play nicely with others I'd never mention it. The audio was recorded on a zoom and added to the video tracks by whatever magic the guy uses. Beyond me. But we did discuss the problem and he agrees and even told me what he did wrong ... again, beyond me.
Ahh, the joy of playing live
