Not at all. Even they're REALLY heavy, niche artists get supported as much as is possible. T&N does that as well. Its a shame that some artists just dont catch on despite the huge push they give their bands.
Starflyer 59 and Neon Horse both had releases last month. The only way I found out they had new stuff was when I actually saw them on the shelves. I found nothing promotional-wise pertaining to those releases anywhere at all.
