Rico, super job... Actually better vocals then most folks here..

Nothing wrong with using backing track, and concentrate on vocals..

Very few folks can comp themselves while singing... and get the best results.. In truth most record their playing as a track and then sing over it..

I have found great players, prefer not to sing, and appreciate the music more..

Great singers usually lack the skills that average players have..

Whatever makes you comfortable.... stay with it...

Again, very decent vocal...
