LSR (short for Lord Sitar Records) started in the mid 60s as a music mail-order business by 14 year young Beatles-fan Barry Tenenbaum. Expanding distribution resulted in Dutch East India Trading which soon after also began releasing vinyl records. By 1983 Tenenbaum founded Homestead Records and around 1988 Rockville. More on him in the worthwhile Magnet 2006-08-25 article.
