These were all on the RCA/Victor/BMG label. As jaybird100 points out, there's also a slew of Henry Mancini and Tomita albums on Dolby Surround CD from the same label. I've got eight Mancini's that I'm aware of so far, and four of the five Tomita's that I'm aware of. I also recently saw two Arthur Fiedler Dolby Surround CD's, but passed them by because they weren't cheap enough and I was totally unimpressed with the mix on his "Greatest Hits of the 70s" Quadradisc.
The key in quickly identifying any of these discs while perusing used CD's is the spine of the CD. Nearly all of the RCA/Victor/BMG Dolby Surround CD's that I've seen have silver spines with the inverted striped red triangle and blue circle logos to one end. But, you can see two exceptions to that "rule" right there in the photo. And many of the RCA Red Seal stereo CD's will trick you into looking at them also because they carry very similar looking indicators on the spine. The last Mancini I came across didn't fit the rule either: I think it was a full color spine instead of silver, and it was only the "double-D" logo and "DOLBY DIGITAL" on the front that caught me. So, the spine is not a hard and fast rule, but it's a pretty good starting point.
I think it was some of fredblue's posts that alerted me to the Mancini and Tomita Dolby Surround CD's about a year ago. Before that, I was totally unaware of Dolby Surround CD's. Since then when I find one, I look at the "also by this artist/also in this series" info in the inserts, and end up walking out with a number more discs than expected!
