I played in cover bands for hundreds of years. One of the favourite changes the drummers like to make is increasing the tempo dramatically to suit their excitement for the show.
This provides a platform for the other musicians to simplify their parts, and get to the bar at break earlier, and for longer.
Time at the bar slows down the second set and provides a more relaxed approach to tempo, timing, and pitch, complemented by an increase of guitar volume aprox. +12db.
