Inger Lise Rypdal - 830s (1974)

"830 S." (the full title on the original release was "830 S. – Bak Sølvmikrofonen med Inger Lise og Stein") is a collaborative compilation album by two of Norway's leading pop stars of the 1970s: singer Inger Lise Rypdal and singer Stein Ingebrigtsen.

The album was released in early 1974 on the young but rapidly gaining momentum Norwegian label Talent. The album was a huge commercial success in Scandinavia, reaching number four on Norway's main VG-lista chart and remaining on the charts for 15 weeks.

The album's title, "830 S.", refers to the state standard for silver purity in Norway. This is a subtle metaphor by producer Arve Sigvaldsen, referring to the performers' "silver," pure, and noble vocals, and also hinting at the subtitle "Bak Sølvmikrofonen" ("Behind the Silver Microphone").

During this period, Inger Lise Rypdal (then performing simply as Inger Lise, married to renowned jazz guitarist Terje Rypdal) and Stein Ingebrigtsen were driving forces in the Norwegian pop scene. This release is essentially a split album and a collection of their biggest hits, singles, and rare recordings, compiled by 1974.
