I'm 41 and started collecting records when I was a bedroom DJ in the 90s, collecting Drum n Bass, UK Garage and Hip-Hop singles. At the same time, I collected rock, pop and other music on CD, and particularly Britpop! In the 90s, there weren't many rock and pop albums being released on vinyl, so I wasn't able to really collect. My rock and pop albums were mainly a few albums my Dad gave to me, like War of the Worlds, Michael Jackson and the Police.
After I stopped DJing, I continued to collect CD only until around 2004, when I bought Anaal Nathrakh's Domine Non Es Dignus on vinyl, and released that vinyl was starting to become more widely used for album releases in the metal genre. I collected vinyl for a while, splitting my money between bargains from metal distros like Todestrieb Records and Blackmetal.com, picking up new albums for around £14 per release; and second hand albums from record fairs, picking up 70s and 80s music such as The Police, Black Sabbath and funk and motown releases. I have now reverted to mainly CD as the mass market revival of vinyl collecting has led to pressure on record presses and a spike in prices.
