Judging by your profile- you probably wont hear anything that will blow you away but it should still be a fun time. The first time I saw Primus was back in 1992- at the time I was totally freaked out by Les so it seemed like the most amazing show I had ever seen.(I went on to see them about 4-5 more times after that) I have grown alot since then as a player and listener and Les' tricks dont impress me like they used to but he is a hell of a showman. If its a good/laid back time you are looking for, Id say go... If you are looking for a life changing bass experience.....you may be dissapointed.
Just my 2 cents worth.
