Well, if your playing by yourself, chords are kind of a must. If you are playing with someone else, and they can play chords, try a blues tune?

ARe you writing something or covers?

make sure you dont just play a one stringed song or youll get a pathetic crowd reaction...playing a song with chords is essential to pleasing a crowd, and if youre not playing chords because they are too hard, then you probably shouldn't be performing...not to disuade your dreams hombre, but I'd hate to see you give up because youve embarassed yourself...and ive been playing for 13 years, so if youre wondering why im telling you this, its probably because i was there at one point, and wish someone would've told me to slow down and practice before trying to show off my skills i didn't posses yet

Hmm. Tears in Heaven. Try that.

Hmmmmmm... I think you need to have someone backing you up if you are going to perform in front of others for the first time. It takes the pressure off of you just a bit. But if it is something you really want to do, alone, then learn the chords of the song, there bro. It will fill in the spaces, tremendously.
