Saw the Misfits and Megadeath play at Harpos, I don't know about the Machine shop, I see a lot of ads for the place, wouldn't hinder be more suited for Soaring Eagle Casino...
Great Place to see a Gig. They have a Killer Sound system. last time I was there was bout 6 yrs ago. Used to play there 8/9 yrs ago in one of the cover bands I was in. Great place for a show, regardless of what side of the stage you are on.
The MS has a pretty wide range of artists, from near Death/Speed metal, or oldschool metal rock, to some Rockabilly that will put your dick in the dirt, and then some southern rock and what i call Hard Country now, not quiet contry, not quite metal (yes i meant to say QUIET Country and Quite Metal. lol).
ahh the weekends at harpos...slayer, cannibal corpse and steel pole bathtub...fond memories. pantera at the state fair coliseum was the shit though. wife got a dollar bill signed by the entire band there. RIP Dimebag.
