They were badass when i saw them in 2010 and played a good variety of songs from the entire career. The cool thing about Primus is that they'll change up their setlist from show to show, so usually they dont play the exact same songs or in the same order.
And they're definitely an original unique band. Personally I attribute them as being the most original band of all time simply because there has been nobody like them before, during, or since them. Les Claypool is just one talented weird individual with a tremendous gift. There will never be a band purely like Primus or Les Claypool.
