If you liked the music then, it's still going now, still growing, still developing, still nurturing great singers and songwriters.
If you're near Boston, or you visit, Club Passim in Harvard Square is still going strong, in its 47th year. It was where Joan Baez and Tom Rush got their start, in its earlier incarnation as Club 47. If you wanna get an idea of what's happening in folk and acoustic music, try the website
www.clubpassim.org --they stream live, but bandwidth is limited, so get there early. And click on the websites of performers from the schedule and you'll get mp3s or wma's of their music, a lot of which is great.
So lemme see, good people from the last twenty years or so of folk/acoustic (god, there are more than I can think of offhand), maybe start with
Tracy Chapman, Shawn Colvin, Bill Staines, Greg Brown, Nanci Griffith, Richard Thompson, Kate Rusby, Eric Bogle, Silly Wizard, Altan, DeDannann, Allison Krauss and Union Station.
Newer hot ones: Antje Duvekot, Lori McKenna (just on Oprah--yay, we're cracking the mainstream), Richard Shindell, Dar Williams, Ellis Paul, Mark Erelli, Jake Armerding, Crooked Still.
