I think a lot of Muso's over play parts now instead of putting the song as the most important thing. Also a lot of Drummer and Bass players get bored easy just grooving on a song. They write interesting bits instead. As such they play above and out of the abilities for the parts. And then suck.. (I have had a guy come in and asked about beat dectective as he cannot play the fills he wants in time
We are talking before they even setup
)
As the drums are the cornerstone of the band, if they suck your in trouble. You can always talk to the bass player, guitarist or vocalist later.
I normally only use a click if the band brings one in.
