I play in well over a dozen bands regularly and perform tons of songs each week. Needless to say, it's sometimes difficult to memorize and recall the 100+ songs I'd play in a week's time. One band I play in just asked me to not perform with a music stand any more. Now, this band doesn't pay the best (usually 100-125 a night) so I'm half tempted to just tell them to find someone else. But that leaves me wondering: what price per gig would you put on memorizing 3 sets of music? This is keeping in mind that the gigs aren't a weekly thing; maybe two shows a month at best. Only one other gig I've ever done has hinted at the "no music stand" rule, and that was a very well paying gig that had multiple 4+ hour rehearsals before the performance. But even then, I've done my share of backing sizable artists and have always been able to have the music handy. For the record, I'm not one of those people who puts the music stand in their face; mine is always off to the side and set rather low so that my whole body is visible to most of the audience.
