While the streamlined maintenance of concert toms has always been something of a draw, I can't abide their asymmetrical appearance or their one-dimensional tonality. In the first case, toms without bottom heads look misshapen to me, a visual effect I find repellent. In the second case, resonate heads do a great deal to add complexity and character to drums. Removing them limits one's tuning options considerably. For the aforementioned reasons, concert toms have never been part of my setup. That report is unlikely to change.
If I found a really cool vintage concert tom kit, I might snatch it up. I had concert toms in the 70's ..... and I briefly re-visited 'em 10 or 15 years ago. Premier Baron kit. Had to sell it to a Premier collector. Drums come and drums go.
I mean, if I were in a position remotely like Thomas Lang, where it was entirely feasible to have many, many kits? Sure, why not with some concert toms? They sound great in the video—perhaps due to processing—and they do have that nostalgia thing for many of us. I don't think I'd ever choose concert toms for my one and only kit, but maybe for my fourth or fifth.
