I play jazz and jam bands. club gigs are always no more than 3 - 45 minute sets for the jam bands, 2 - 45 minute sets for the jazz bands. concerts are always 1 - 90 minute set. for the occasional wedding it's 1 cocktail jazz set and 3 rock sets. but that's for serious $$.
I quit playing 4 hour club gigs back in the 80's.
