Most enjoyable gig I've been to was Testament in Sydney, I think '07 or '08. Classic lineup with Bostaph on drums. Apart from maybe one or two songs, everything else was from the first 5 albums. Chuck Billy's voice was booming. Skolnick schooled everyone on guitar that night. Opened the set with Over The Wall/Into the Pit and everyone went mental.
Edit: found the set list

That was the night of the hawks/cats grand final....
Had a bunch of mates over for a big bbq to watch the GF (mid-morning start), and was absolutely munted at the gig. After the gig, some of said (scouser) mates then wanted to kick-on and watch a liverpool match at stupid o'clock (i think they were playing everton, so was a bit of a big deal), at which point i bid them good evening and stumbled off..
Show was great (as much as i can recall), but their tour a couple of years earlier at the manning bar (nick barker ex-COF on drums) was better. That was an awesome show, apart from the shiner i copped getting a stray accidental doc marten in the face as 200 people (including me) stormed the stage during 'over the wall". Good times haha.
