To mark the 60th anniversary of the Beach Boys’ Pet Sounds, Interscope-Capitol has released a limited-edition Definitive Sound Series One Step version of this landmark album. Tom “Grover” Biery, who oversaw the project, tells of its unusual sourcing, which involves the 1972 master of Pet Sounds that was released as part of a double LP with the then-new Beach Boys album Carl and the Passions “So Tough.” Why was that 1972 Pet Sounds so revered, and how did it come to be used here instead of the original 1966 mono master? How does this DSS version differ from the mono/stereo Pet Sounds that Universal's Vinylphyle series just released? Do people buying these new Pet Sounds versions already own multiple copies? (Raises hand...) Biery also produced One-Steps from Dr. Dre, Beck, R.E.M. (as previously discussed on Caropop), Tom Petty, Green Day and Prince and the Revolution, and he explains why the quality justifies the price.
