I have all of Summoning's albums on LP (including the ultra limited editions with Silenius/Protector's autographed cards) and first edition CDs + represses. Also I have all their album cover official shirts in tee/longsleeve/hoodies; don't really wear them anymore tho. Without a doubt the only metal band that matters to me.
I also have MANY extremely rare cassettes, LPs, first editions, shirts, boxsets, etc. of older bands but really don't care about them anymore. Just for fun, I will mention a few of my rarities:
1. Nargaroth - Semper Fidelis box set (#70/99) : I had to write a letter to Kanwulf (Ash) to even be considered to get one. I did get one and it is considered one of rarest of all BM items in existence; he picked out personal items to include in each one, so none are the same. Most recent sale of one box (7 years ago!) was almost 1000$.
2. Emperor - Wrath Of The Tyrants cassette/CD on Wild Rags
3. Silencer - Death, Pierce Me PIC LP in Sleeve by Autopsy Kitchen (less than 25 in existence)
4. Myrkwid('s) first four demo tapes - less than 50 hand numbered of each in existence and took FOREVER to find them.
5. Gorgoroth - A sorcery written in blood demo tape (1993) : direct from Warloghe member, who obtained it directly from the band in 93, when the band mattered and Hat was still on vocals.
6. Abyssic Hate - Betrayed demo tape : direct from Warloghe member, who got it directly from Shane Rout.
7. Abyssic Hate - Suicidial Emotions PIC LP (4 copies, all of which are written/produced in the single digits or teens out of 500, the lowest being #003).
8. Burzum - Support your local Einsatz Kommando tee and longsleeve: While in prison, Varg Vikernes had these printed in limited numbers and are banned in MANY EU countries.
I plan on selling almost everything eventually, bc I really don't listen to BM anymore. I would rather see them go to caring homes than collect dust in mine. I guess my ever evolving tastes in music changed into more electric, happy music.
