I drove from Ottawa with my family to Barrie to visit some friends for the weekend! I ordered a ticket that day and drove to downtown TO by myself that night to see this show!
Missed Weedeater unfort, woulda missed Melvins too (had they been there) but caught Voivod (you really should give them a listen) They were really good actually! They may not be your cup of tea though by the sounds of it. Ive been a fan since the early years and seen them quite a few times. It was great seeing Phil sing Nothingface with them!
As for Down, it was my 5th time seeing them and again they were on fire as you mentioned! I have seen them on 2 different Evenings with Down and although those nights were far more superior due to the longer sets, this was still a great show! Got a good number of pics and vids from it! I love the Kool Haus, great venue!!!
Really worth the trip form Ottawa->Barrie->Toronto->Back to Barrie in one day!
