This is a Very Rare Fulton LP. The piece by Mozart on side one has a true 16 cycle note. Since it has virtually no overtones, the note is more often than not completely undetectable; few stereos in my experience have ever been able to reproduce it. If you have a full-range system, this record will allow you to hear deep bass you may have never heard before.
Let me warn you that these records require extremely transparent, full-bandwidth, neutral stereo systems to sound their best. Most records are “goosed up” in various ways to play on any stereo, regardless of quality. These are the opposite. From my admittedly prejudiced point of view, tubes are an absolute must for the magic of these live recordings to come through. [Or so I thought in 2006. Now, not so much.]
If your system leans more toward the budget side, these Fulton records will leave you wondering what in the world that Tom Port character was talking about.
And of course organ records require good deep bass, the hardest part of the frequency range to reproduce in the typical living room. With this organ record at least you’ll know what the goal should be.
