December Underground came out when I was 16. My then boyfriend sent me Prelude 12/21 via IM, which took hours to download via dial-up. I had to sneak to listen to it (strict parents), then later skipped school to go to FYE one town over to buy the CD, which I had to hide between layers of Mercy Me & Vivaldi. This album was my constant through my angsty, awkward teen years, and remains an album I enjoy revisiting as an adult. (I had to buy a new copy as I wore the old one out.)
