Nice to see some metal on here... my favorite genre! That is awesome that you got to see Sepultura in their original format. "Arise" was one of the first CD's I ever had and I probably played that CD until it died. They've gone through a lot of changes in the band over the years and I am not sure about this but i think only the original bass player remains.
Roots is one of those songs that I could listen to on repeat and when I work out it is a massive motivator for me.
I remember many years ago back in the 90's when the rest of the world was giving out Grammies for pop bands like Brittney Spears and what not, Brazil gave Sepultura the "best song" award to Sepultura for "Orgazmatron" and at that point in my life I was thinking Brazil must be the coolest country in the world.
The whole album "roots" is just one of the best albums ever made. Sepultura and the cavalera brothers meant a lot for Brasil, they brought the brazilian culture combined with world-wide adopted music together... Just love it !!! Just like Max'es Soulfly, just as awesome... I got the Soulfly logo tattooed om my back ;)
Have a great day and thanks !!
