Often used to describe bands like Pantera and Exhorder. With mid-tempo riffs similar to those found in Thrash Metal and a tendency to focus more on groovy syncopation and heaviness than outright speed.
Good for you. I performed at the Fringe festival back in 92. Went with a fledgling U.S. touring Shakespeare company from Virginia-we were called Shenandoah Shakespeare Express back then. It's actually grown into a pretty thriving institution in Staunton Virginia. Just looked them up, American Shakespeare Center. It literally grew out of a group of college kids from James Madison University and a charismatic Shakespeare proff in the late 80's.
Stupid idea of the week? Staying out till 1am on Thursday night/Friday morning drinking with younger colleagues from work. In my defence I was in Edinburgh which is probably my favourite city I have ever visited and I have not been able to go for the past 2 years because of the pandemic.
