thatwasthen live at King King Flyer
After rocking out at The House of Blues, thatwasthen returns to King King for another night of blues inspired, original classic rock. Thanks to everyone who came out to HOB, but if you missed it, here’s your chance to see us in a much more intimate setting.

Smog
I’ve been in Los Angeles for about two years and up until now I’ve never really considered myself to be affected by this foreign environmental anomaly that you Californians affectionately refer to as Smog.
"Smog, are you farting up some more death?"
Sure, I’ve seen it. How can one not? Now, you must understand that in Rhode Island (where I lived previously) we do not have smog. The air is much cleaner and is more or less free of the noxious amalgamation of carbon emissions, taco stand fallout and the homeless decay. I’m not saying it’s perfect, but it doesn’t do what I’m about to explain.
A little about Los Angeles:
- Almost 15 million people
- 22,000 miles of roads
- 5 million licensed drivers
- who the hell knows how many un-licensed drivers
- and up to 3 dogs per house (the sidewalks are covered in dog-shit)
Al Gore: Inventor of The Internet and The Flamethrower.
When I step outside to take a walk, I breathe in my first breathe of air and almost feel as if I’m in an abandoned 15 week old sushi joint, upside down, with a small midget sending assorted raw beefs through a woodchipper in my general direction: sick. I guess it took a while to set in. Perhaps it’s gotten worse this year than last. I’m not Al Gore. I really don’t know.
One reason why I’m psyched we’re booking outside of LA:
- I will get to breathe clean air and feel the amps shaking the stage beneath my feet while rocking out for people who have no idea who we are.
Sonic Boom Heard over Los Angeles – ‘Guile’ to blame
guile: possible cause of the sonic boom.
Half of Los Angeles was just scared out of their pants by a loud boom on this 9/11 memorial friday. for those of you frantically searching ‘what was that loud noise‘, here is the answer. thankfully it was not another terrorist attack.
from Wikipedia:
The term sonic boom is commonly used to refer to the shocks caused by the supersonic flight of an aircraft. Sonic booms generate enormous amounts of sound energy, sounding much like an explosion. Thunder is a type of natural sonic boom, created by the rapid heating and expansion of air in a lightning discharge.[1]
Causes
When an object passes through the air, it creates a series of pressure waves in front of it and behind it, similar to the bow and stern waves created by a boat. These waves travel at the speed of sound, and as the speed of the object increases, the waves are forced together, or compressed, because they cannot “get out of the way” of each other, eventually merging into a single shock wave at the speed of sound. This critical speed is known as Mach 1 and is approximately 1,225 kilometers per hour (761 mph) at sea level at room temperature. In smooth flight, the shock wave starts at the nose of the aircraft and ends at the tail. Because directions around the aircraft’s direction of travel are equivalent, the shock forms a Mach cone with the aircraft at its tip. The half-angle (between direction of flight and the shock wave) α is given by
,
where
is the plane’s Mach number. So the faster it goes, the finer, (more pointed) the cone.
There is a rise in pressure at the nose, decreasing steadily to a negative pressure at the tail, followed by a sudden return to normal pressure after the object passes. This “overpressure profile” is known as an N-wave because of its shape. The “boom” is experienced when there is a sudden change in pressure, so the N-wave causes two booms, one when the initial pressure rise from the nose hits, and another when the tail passes and the pressure suddenly returns to normal. This leads to a distinctive “double boom” from supersonic aircraft. When maneuvering, the pressure distribution changes into different forms, with a characteristic U-wave shape.
Since the boom is being generated continually as long as the aircraft is supersonic, it fills out a narrow path on the ground following the aircraft’s flight path, a bit like an unrolling celebrity carpet and hence known as the “boom carpet”. Its width depends on the altitude of the aircraft. [2] The distance from the point on the ground where the boom is heard to the aircraft depends on its altitude and the angle α.
