Guitar. Haven't had a band in a long time, when you like metal (real metal not radio metal) it's hard to find others who A:) Like the same stuff that you do. B:) Are good enough to play said music. Also good drummers are hard to find. It's either the dip#$%* who doesn't know how to play anything but blast beats, or the guy who can't play them at all! Ok. I'm done ranting. 
That reminds me of one of the funniest experiences I've had with music- the last band I was in went through a period of time where we were constantly interviewing drummers. Two of the most interesting people that auditioned were as follows:
1) Young "kid", maybe 17-19 years old, comes in and has a cocky attitude from the get-go. Is wearing a shirt that is a button down, with only the very bottom buttoned- I'm thinking, why bother? Or, wouldn't a tee-shirt be much more comfortable? This guy smelled of BO so bad, it followed him around like a terrible stink cloud. Anyway, we start the audition (of which this dude has already had a cd of our music for a week to work on).. He is absolutely TERRIBLE- I mean, not only was he not playing the drum parts at all, but he was not even close to being on time! Instead, it was more like every song he just played an extremely loud, fast, and extra-terrible drum solo. Then at the end of the audition, he asked us when he could start. We told him we had other people to consider (being polite!), and he says "you guys aren't my style of music anyway- I'm outta here!"
2) Crazy older dude.. We play rock, and are in our early 30's. This guy comes in, is like in his late 50s, has crazy twisted sister hair, brings some chick to the audition who just sat in the corner and didn't say jack to anyone. He was a last minute audition, and hadn't had the luxury of getting our music CD in advance, so we told him we'd play each song for him in advance, and then he could play that song, etc. He'd listed to the CD for like 5 seconds, then stand up and tell us he had to get a smoke and make a quick phone call. Then he'd come back in, and he'd play the song perfectly, without really hearing the CD! He was clearly talented, but he has insane scheduling issues. Oh well, he was a character.
