The choice of musicians and audio engineers is generally pretty solid; the likes of Pink Floyd, Telarc, Sting, Tom Petty, Doug Sax, Mark Knopfler, Lenny Kravitz, Warner Bros, Disney, Hans Zimmer, Rolling Stones, CBC, Sony - SACD, Ronnie Scott's Jazz club, Peter Walsh, James Guthrie...etc. People within the business are more likely to make solid long term choices rather than the latest and greatest fad.
