On Google Saturday I read that mammoth had canceled two shows one being the commerce City which is our Denver show due to band members having covid virus. I'm demanding a full refund due to the fact that Mammoth was my whole reason for going to the concert. I lost my sister this year during the pandemic along with Wolfgang losing his father the last concert I went to was 2012 Van Halen and I watched Wolfgang at age 16 performing. Covid has taken so much. Refund us! User's recommendation: Don't pre buy tickets.
