I dont always listen to growly metal, but when I do, its Ghost of Perdition live at Red Rocks!
My son has been trying for months to get me into Opeth. (Funny he first heard Opeth when we were in my car listening to a "recommended" playlist based on my likes). He said "their new music isnt growly", but it just wasn't clicking for me.
Until last weekend when I sat down and watched Garden of the Titans. Loving it! Its melodic, heavy, beautiful and the growls arent the entire thing.
