Yet another installment in the "Do you own [INSERT ALBUM]?" series.
Nirvana's Nevermind. Released in September 1991. The harbinger of "Seattle Grunge Rock" that marked the end of "glam rock" and "hair metal".
I bought it when it first came out. It was kind of hard not to. As soon as it was released, it was blatantly obvious that it marked a major shift in rock music and popular music in general. I disembarked the Grunge Train soon after, focusing my listening on blues, jazz, and classic rock.
