I've been looking through my stuff and really don't know if there's anything I've listened to, all the way through, more than Sonic Youth's Evol. I bought it on cassette tape when it came out in '86...didn't know SY yet but was drawn to the overall aesthetic - the scrawled text, the song titles, the image on the cover, the name of the band...
It was a weird love at first listen but it definitely was. It's probably the most influential sound for my subsequent musical loves - arty, damaged, noisy-ness anchored by melodic hooks, female/male vocal interplay, squalling guitar atmospherics, etc. That tape is the reason I've continued to have a tape deck in my life for all these years. I resisted ever getting the cd 'cause it didn't seem right or necessary but recently picked up the remastered vinyl (pink even!). Sounds great, not too much tweeking of the orig. sound but a good improvement on my 26 year old tape. I still put it on every month or two for a late night session.
