Good evening! Sorry for the long time between post and replies . Hello!
OK, so by decades, seriously, i mean 20+ not quite 30. First band I was really into was Metallica and still really love the 80s and early 90s material. Though I'm a child of 1980s my dad listened to Deep Purple, Rainbow, Neil Young so probably exposed to 70s bands early on and started from being a nipper. We were both listening to Rammstein at the same point! As for what bands I'm into, lots! Metallica, Guns & Roses, Marilyn Manson, NiN, Devil Driver, SOAD, Korn just for starters. Been listening to a lot of NiN recently and got into Dutch prog rock band Focus. There's a few dates in UK that Focus are playing and will try and go along to see them.
