Of course there are dozens of other bars that might be hosting something all the way up to 70,000 or so at Ford Field for major events. You will need to check your dates to see if there is anything going on that interests you. Motor City does have a small theater venue (1900 seats). That leaves V at the MGM Grand which does not get great reviews. It also looks like Amnesia at Motor City is only available for private parties now. I thought Greektown had built one, but apparently not. You might find a cover band playing in one of the casino bars on a weekend, but it is hardly enough to keep you entertained for three days without leaving the property. They are primarily about gambling with a side of drinking mostly frequented by locals. They are all roughly the same - and boring when you come right down to it.
