I 2nd this! Honestly, I hear nothing but a professional doing his work. You have nothing to apologize for.You have no apologies to make for your playing in those demos. You exemplify the talent shown every day by the working drummers of the world who make a band groove. The famous get the accolades, but it's guys like us that make the local music scenes live on. Thanks for the inspiring testimony, and for the drumming. God bless.
Actually, say you're sorry right now for doubting your skill!
