Nervousness comes because we're thinking about ourselves, not the audience. The audience, usually, paid good money/invested their time to see a professional music performance. So focus on giving them that and not on yourself and you'll be fine.
The best live acts in history seem to have one thing in common: they focus on "giving the fans their money's worth". Not, what will *I* look like/sound like/perform like. KISS never wrote the best music, but they put on some of the greatest shows in history because of that philosophy. Led Zeppelin stole half their music from poor and/or dead blues musicians, but also put on some of the greatest shows in history because of that philosophy. Megadeth, Yngwie Malmsteen and other very talented players notoriously have awful shows because they're focus is on themselves, not giving the fans their money's worth.
With that in mind, in the future, target playing gigs where you know people who dig what y'all play will show up, give them their money's worth and it won't take long before you're packing venues and getting gig invites left and right.
And get a singer. A man/woman who can not only compliment the music vocally, but work the crowd to give them their money's worth. Most non-musicians imprint on the singer cause they see singing as something they can relate to and secretly believe they can do as well, even if it's only in the car by themselves with no one to tell them they're tone deaf and so far out of key a locksmith from Juliard couldn't help 'em.
You got this brutha! Break a leg!
