I have a few Swedish CDs in my own collection....two from the old Swedish Radio compilation project from the 1960s, issued by Caprice--"Ancient Swedish Pastoral Music" (CAP 21483 E) and "Vall-, Trall-, and Lapp-Nils Låtar" (CAP 21489). These are mostly field recordings, not the best sound quality, but the "Pastoral Music" one ends with a 30-minute 'concert' done with kulning and horn-playing around a lake. "Pastoral Music from Malung" (KRCD 26) is another of the same sort. "Visfolk och Tralltokar" has a younger generation of callers, such as Britta and Maria Röjås, Lena Willemark, Agneta Stolpe.
And then there's Maria Röjås' new CD "Silverringar små och stora", on which she tralls a lot of the songs--I think there is also some Kulning.
