Five tunes from one of the best bands that exists today certainly isn’t enough, but Castle Black make the most of this quick listen as they find a unique spot between grunge, punk and New Wave. Each song here highlights something different about their extensive talent, from atmosphere and rhythm to driving, charged, melodic intensity and even a ballad of sorts with bursts of abrupt fury.

In a world that lives in a bubble of unspeakable acts and in a time that few artists speak through music for social issues comes CASTLE BLACK with ‘Sierra’. Taking to issue all of the tremors that are shaking the world today with the punk and tone strong voices can only make, you feel the entirety of the pain felt by many and more than you can imagine.
