Just listening to Harbinger Of Metal, and by goat it's slooooww... track 4's about 20 minutes long, and about 10 minutes of that is the most lysergic, lurching drum solo ever... it just keeps stopping, then you think 'here's where the crashing power chord's gonna come in...' - but then it doesn't, there's just a pause and another drum roll, then again, and again... it's an agonisingly anti-climactic work of genius in its own right...
