Think we probably have similar tastes - my all time favourite show was At The Drive-In playing in a tiny tent at the Reading festival in Aug 2000. I also saw ATDI and Trail of Dead on the same Dec 2000 tours as you - they were back to back with ATDI at the Camden Electric Ballroom on the first night and Trail of Dead the following evening at University of London Union (supported by some unknown band called Snow Patrol who were shite!!). Funnily enough, the last gig I went to was also Trail of Dead, a couple of weeks before lockdown.
