1812 Overture *

Telarc DG-10041. Side one. "1812" Overture, Op. 49. This digitally recorded and mastered LP from 1979 is reputed to have the highest velocity grooves ever produced on a commercially available record. The cannon shots' initial "cracks" lie in the area between 2,000 and 3,000 Hz. The "booms" contain components as low as 6 cycles.

Jim -- I can remember trying to identify passages on my LPs, but nothing as dramatic as this "1812 Overture"!

Hi, Peter. Yes, this is an actual LP.

It’s amazing to look at and hear. Although this may be done on other LPs, one striking thing about this one is how they adjusted the spacing between the grooves in anticipation of the loud passages so that the modulations would “fit”.

Although there may be other cartridges which can track this LP, at that time (1979) the one I owned which did the job was the Shure V-15 type 5MR. These are still made and I still use one to this day. As I understand it, many cartridges not only "mistrack" horribly, but actually do get knocked out of the groove when attempting to play this record.

It is an amazingly good sounding recording if the system can handle it. It's also the only record I have where you can clearly see the groove modulations with the naked eye. I believe that this recording is also now available in CD format.

When I saw the theme of this challenge, I immediately thought of this particular record.

This weekend is the annual Wyoming Cannon Shoot. Black Powder cannon enthusiasts from around the country will be there so I’ll get a chance to take some photos of and enjoy the action there. Hearing protection is a must. But even with protection, the feeling of the impact of the shock waves as they hit your chest is awesome!

Fascinating! That's really a 33 1/3 rpm LP? How does the needle stay in the grooves?
