well...the rolling stones were here last weekend, and they played over 2 hours..it was the cant miss show of the year and the reviews were awesome....as for the xylophone, well, was not what you would have expected..there werent even lyrics, just a bunch of stuff that sounded the same and made you think of band camp...and primus, they were so mellow, everyone was sitting down most of it......the bottom line is, there is nothing to make up for 9 songs..a concert should def be more than an hour....
