Bruckner used to sell pain-killing drug
I suspect that Bruckner could surely have wanted this drug after the disastrous premiere of his Third Symphony.
The CD was issued by CBS Special Products in 1991. Catalog number LSP 46704. On the CD it states, "Aangeboden door DAGRA Dagra Pharma, de fabricant van MS Contin (R)."
A little research uncovered that another work in this "Tormented composers" series of CDs was the Brahms Piano Concerto No. 2.
MS CONTIN is a controlled-release tablet containing morphine sulfate. Morphine is released from MS CONTIN somewhat more slowly than from conventional oral preparations.
My thanks to Elmer Ysebaert for providing this information.
