I have done an open mic night before; I hated it. I did some covers of things like 'Sweet child O' Mine' and 'Oh Well'. They went down well but I just don't have the confidence in my voice to get up on stage and sing well (I am shaky and by the time I'm over that I've done my slot).
Next one to come round I'll do it though; I'll do the jazzy improv piece I mentioned and 'Oh Well' as they are good acoustic songs and maybe some Dylan (can't complain about somebody murdering Dylan's vocal lines now can we?).
I wouldn't mind doing the odd cover but really I am a creative element more than a copycat. I love the ways other musicians work but I can't work that way; Petrucci's solos in HK just felt like my fingers weren't fretting and were just flapping about (sounded pretty much right though) but if I feel the need for a Petrucci style lick I can just play it and it feels natural to me as I'm not consciously trying to emulate him at all. I can play in the style of Satriani but I can't play any of his numbers all the way through.
On a better note; I just had a guitar practise (more of a musical wank but fun all the same

) and I really sorted out my anxieties for a bit but I need to get this ensemble thing together (I need suggestions of simple songs which the other people can learn easily; maybe a Beatles number) and sort out my solos.
FOTBB is just a case of getting my arse in gear and getting out the old metronome, WYWH needs the solos learning (not too bad but Gilmore's solos are hard to get the feel right for), 21CSM is definitely a good one as it's nice and simple guitar parts. That with the jazz improv and a Beatles number is enough I think.
