That's pretty high tech for a product from the 1970s to use a

Ah, now that's a bit of a funny one. Predominantly of Scottish and Irish
origins. It's a bit of an acquired taste. Can be quite effective in certain
types of folk music, but also, can be a wailing dirge in 'native'
stand-alone mode. Can also be very 'stirring' when used for military marches
with drums, and of course, used by nations all over the place to bring the
new year in. And then there was Paul McCartney's "Mull of Kintyre", a lovely
song, but I was never 100% convinced that it was actually genuine pipes on
the recording, and not from a synthesizer, as it sounds slightly too
pitch-perfect ...

I have zero interest in disco -- but I've always wondered why people dislike
it so much. It's supposed to be danced to, not listened to. Why would anyone
want to sit and listen to such fundamentally uninteresting music?

That isn't Bluegrass. I like traditional country music, and
'Southern Gospel' music as well. I've owned & used waltz records, and
classical music but Bluegrass is my favorite.

What most people call 'music' these days, gives me migraines.

The "Blues Brothers" were a couple burnt out druggies.

They dislike it because it is loud, repetitious noise, and listening
was often unavoidable just like 'Rap'.

I used to sell at a flea market on the weekends, and some ass would
set ut a boom box with a worn out tape of Cajun music and turn it up so
loud you couldn't talk to customers. Then he would scream, "Doncha al'
just love this shit?" Some people wouldn't listen to certain types of
'music' if it was their choice, and being forced to put up with it by
morons turns it into hatred.

You as well ? I don't understand this. I am not talking about 'Disco' as in
a genre of music - in fact a whole lifestyle - which has long since faded
away. I am talking about 'a disco (theque)' as in a person or persons who
set up music and lighting equipment in a venue for the purposes of providing
the musical entertainment for a dance event, or a birthday, or a works
celebration, or a charity do, or whatever. The music played can be anything
from rock, pop, folk and yes - even 'disco'. Do you not have such travelling
music providers stateside ? Is this where the difficulty in understanding
what exactly I am talking about, is coming from ?

I like my Bluegrass from Kentucky, where it all started. :)

I also like 'Bluegrass Underground' which is performed live in a
large natural cavern in Tennessee:

http://www.bluegrassunderground.com/ and can be hard at
www.wsmonline.com just before the Grand Old Opry.

(Bluegrass Underground airs every Sat night on the Legend, 650 WSM. The
station where Bluegrass was born is home to Bluegrass Underground every
Saturday night just before The Grand Ole Opry at 6pm EST.)

In the US this is usually called a "mobile DJ" service. "Mobile"
because they come to your location with records, amps, speakers, etc.
DJ means "disk jockey" - a person who selects and plays recorded music.
People will say things like "We should hire a DJ for the party."

The DJ has usually brought amps and speakers and maybe some lights. He
(most common) or she (sometimes) used to bring a stack of (records|tapes|
CDs) and a (turntable|tape deck|CD player). Today the music comes from
a laptop or MP3 player, but everything else is the same.

By itself, "DJ" can also be the person that works at a radio station,
introducing songs and playing them. A "DJ" can also be the person in
a hip-hop group who plays records to back up the singer.

If you are talking about a building where people go to listen to
recorded music, dance, and probably drink alcohol, that's usually called
a "club" or maybe a "bar". It was called a "disco" in the 1970s but not
any longer.

As you have probably figured out, if you say "disco" in the US today,
people generally think of the late 1970s music style - "Saturday Night
Fever", etc.

OK. That makes sense then. Your 'mobile DJ service' is exactly the same as
our 'mobile disco'. It sounds as though lighting is not a significant
aspect, but would probably be known as DJ lighting, and the rest of the
stuff - amps, speakers, CD decks etc - as DJ equipment. Here, although those
terms are used, it's all better known as 'disco' equipment or 'disco'
lighting. Audio and lighting equipment for sale on eBay is usually described
as 'DJ' equipment. The guy I was out doing the lighting for last week, calls
his service "Occasions Disco". In the past, I have done light shows for
"Force 8 Disco" "Hot Wax Disco" and "Disco International", among others.
Back in the day, it was, as you say, all run from records and decks, or CDs
and dual CD decks. The one I was out with last week, was all run from a
laptop, although the physical lights were driven from a separate custom DMX
controller. Visualizations via a video projector, were from another laptop,
fed through a video mixer to allow a video camera on the revelers, to be
overlaid on the visualizations.

So, now that's all cleared up, we will all know that when I talk about a
disco, I'm referring to a mobile DJ service, and not the music genre /
lifestyle ... :)

I thought I spoke pretty good American, having been there many times, and
having spent years on usenet talking to Americans, but this seems to be yet
another good example of two nations divided by a common language ...
