An absolutely amazing melodic, metal band. Album Dead Years
was released in 2012 and it is simply the best album to be released in years for me. 11/10.
Shai Hulud is not headlining because they don't have any draw. Putting aside them being considered a legacy band, people don't know them really these days so that's a surefire way of underselling a tour. It always surprises me when people seemed annoyed by this, the headliner isn't necessarily the "best" (though in this case This Or The Apocalypse is far and away the best for me) but rather the one who will draw the most tickets. That said, Sworn In will probably draw the biggest audiences.
