It's not like I didn't know about Americana artists. I read enough music magazines that I knew what names were getting rave reviews. John Morthland's essential 1984 book, Country Music, opened my ears to a lot of Country music outside the Country charts. This is all similar to my experiences with Alt-Rock. It wasn't until I started reading Spin or Option magazine that I started to explore that genre. I skipped most of the important bands in the 80's.
Listening to KPIG in the early 90's, the album that really turned me on to the Americana genre was John Prine's 1991 comeback, The Missing Years. His first studio album in six years. Once I fell in love with it, and hearing other Prine cuts, I began to explore other names in the genre thanks to KPIG.
Some 35 years later the Americana genre is more popular than ever. I wasn't there at the beginning when it was just a newly named format. KPIG is still going strong. And I've been along for the ride ever since.
Here's a Spotify playlist of my early KPIG music memories:
