Do you really need to limit the availability of players by age discrimination?
Our guitarist is 21, both our vocalist are +- 30, our drummer is 40, I and our bass player are both > 50 ?
Sure you have that right. Yet unless you have the intent of being the next great pretty boy band I don't see the point.
I like most of your sounds myself with the exception of the high gain your using which to me sounds tin thin and over-processed.
( having the same issue with my guitarist )
Here is another solicited opinion ... ready ?
Working with a metronome is great rehearsal / practice.
Good music ebbs and flows with intent and intensity of your passions, it's not tempo sterile.
I'd play in a band with you because I like the direction of your melodies.
But alas ... I'm too damn old.
Best wishes.
