they were made by the hare krishna society here in denmark back in the day.
they were sold on the street, directly from the hare krishna peoples, and you paid whatever you feel like paying. i remember back in 95 when i was about 12 i bought "rising sign" on tape. and it was in my walkman for the next loong time. dont know where it is today though.
anyway, the cds are not that hard to get for me who lives in denmark. i have also sent a handfull overseas, over the years i will keep my eyes open for them again.
