I had concerts in the 70s, loved em. I started off with the Pearl Full Dimension set up; https://www.pearldrummersforum.com/attachment.php?attachmentid=439440&stc=1&d=1354542791
Mine was in White, then I started adding the smaller ones, 6", 8", 10", 12" so eventually I had the whole set of 8 concerts.
After some time I eventually ended up with just 5 concerts,8",10",12",14",16" wrapped in plastic bags (for protection) inside one another, they were fitted in a Kick drum an a F/t case The cases each had a sheet of wood, screwed to the bottom with rubber castors. So I would turn up at a gig, and it was "pack n roll all the way", whilst my mates were struggling with their heavy amps!.. Happy days...
