My first and main passion has always been the many genres of metal. No matter how many other genres I listen to, I will always come back to metal. I have a lot of interest in NWOBHM, tech death, and prog metal. I will also listen to metalcore and nu-metal very occasionally, though too much of it sounds similar nowadays.
Ibanez guitars are another main passion for me, I love looking over old catalogs and seeing all the old discontinued models. I also like Blackmachine guitars, though I doubt I would ever own one due to the price.
That's about it for now, though more will probably added later.
