Dirty was the first album of theirs I heard when I was 13 and living in the US, so that will always be a favourite due to it being the first one I got into. Experimental Jet Set came out when I was still living there, but didn’t enjoy it as much, so went backwards instead.
There’s a feeling I can’t quite describe to how a lot of the songs from the late 80s/early 90s sound. Songs like Disappearer, Candle, Hey Joni, The Sprawl, Tunic etc. All those interwoven arpeggios and motorik drums. It’s kind of claustrophobic and unsettling, but there’s something warm and comforting there too. I probably listen to albums from that period more than any others.
As mentioned before, they really made me look at playing the guitar in a different way. Before then I thought shredding was where it was at, but after realising I didn’t really have the patience (or the will) to play like Steve Vai I just started fucking around with tunings and odd chord shapes.
I went off them a bit as the 90s wore on and I got more into punk and hardcore, but Sonic Nurse got me interested again so went back and re-discovered all the 80s stuff all over again.
In short, I fucking love Sonic Youth and have been listening to them all day.
