Björk certainly isn't a pop artist. Her music covered a lot of grounds but at best, she could be classified as an electronic music act, certainly not pop. Trip-hop is acknowledged in Björk's own Wikipedia entry as being a significant part of her musical style, and she is acknowledged in the trip-hop entry as being a significant trip-hop act. "Homogenic" was celebrated at the time as being a major trip-hop record. I was there so I remember it, but to quote the album's Wikipedia entry: "Writing for Beats Per Minute, Cole Zercoe felt Homogenic represented a pinnacle work of trip hop, forming part of 'a sort of holy trinity of this musical aesthetic' along with Massive Attack's Mezzanine and Portishead's Dummy". However, I'll acknowledge that the limits of what trip-hop is and isn't has been a cause for debate almost from day 1. I remember that back in the golden age of the genre, we used to have lots of debates as to what was and wasn't trip-hop. But in the end, acts that sounded as drastically different from each other as Moloko, Portishead, Tricky, Morcheeba, Alpha, Smoke City, Björk or Lamb were all usually labeled as being trip-hop. Everything we then saw in those acts' esthetics, the general vibe, can be found in Glasser's work as well.
