David Krakauer live on the Internet Archive
The Internet Archive is the home to the "Wayback machine" and a host of other imperfectly-maintained archives. So, don't rely on the IA for the long-term preservation of your precious tapes. What you can rely on is that there are millions of digital recordings, from web pages to audio and video, available. Sadly, there is virtually no klezmer (and no much more Jewish music in general). The only thing I could find that was longer than a single clip was this performance/interview by David Krakauer (with SoCalled and the rest of the band circa "Bubbe Meises"). I'd say that this recording, alone, is worth exploring further for. Check it out at www.archive.org/details/KEXPKEXPLivePerformances_23
I, myself, have a very few live recordings of various bands created over the years. If you know that I have a recording of your band, and I haven't yet asked, please feel encouraged to email me and let me know that your recordings can be uploaded. It's a great option for me—I have no time to create podcasts, and don't record much because I never have time to listen to the recordings once I've made them. Even getting the recording from DAT or Digital Memory card takes time and energy that I often can't find. But, there should be good, interesting Jewish music that can be found online. I'm happy to help, and even more, I encourage others to participate here, or elsewhere.
