Damn, that doesn't sound good at all indeed. The deceased person is from the RV according to that article (which is of the band, right?). And there are band members amongst the 6 injured in the hospital (of these injured 3 persons are in critical condition). I hope everybody pulls through!
These guys can't catch a break. Googling it reminded my of their 2014 crash, where their equipment was destroyed and they had to cancel their tour. Fortunately no major injuries back then.
