Must admit I don’t know why, gigging in an originals band is much easier, turn up with a bass & bag of leads/tuner, plug in, play 30/40mins, done.
As oppose to turn up at 7 with a covers band, set up a whole PA & lights along with full backline, then play at least two 45min sets, then have to break down all of said earlier gear.
Sure in my old originals band I found that too exhausting but that’s cos it was gigs pretty much every weekend, sometimes both Fri & Sat, all over the country and in Europe, but if keeping to a fairly local patch originals I find a lot easier. Full respect to the covers bands for the amount of work that’s needed.
