I would work on strumming technique before I would concern myself with bpm. Learn how to strum, double pick, down pick, up pick and once you have the technique down, turn on the metronome. YMMV
Actually, funny you'd say that, I do have anecdotal experience. A coworker shared a story of a friend of his who tried to euthanize his dog by leaving it in a running car located in a closed garage. The car didn't produce enough carbon monoxide and he went out later and found the dog sitting there wagging his tail. The cheap SOB had to spend the money at the vet after all.
And with modern emissions, an idling vehicle is hardly a concern for the environment. Heck, you could sit in a closed garage with your vehicle idling and not suffer any ill effects from carbon monoxide. Older vehicles not so much though.
Also the picking technique of these guys is amazing. Not a fan of the vocals but the guitar work is something special. One guy is concentrating as if his life depends on it. The other guy is wondering if he paid too much for that muffler.
Maybe they are waiting for someone and, while listening to the radio, don't want to have to hit the accessory button every two minutes when it automatically shuts off. Maybe they have allergies and don't want too much exposure to the elements.
I'd wager they probably have a pet peeve of people who can't mind their own freaking business.
I went to see Megadeth and Lamb of God last Friday and it was so amazing to be back at a concert. There was a real energy and the bands did not disappoint. They thanked the crowd several times and expressed their gratitude at being able to do concerts again.
If you ever get a chance to do an outdoor concert at Soaring Eagle, jump on it. The sound was absolutely amazing.
I'd heard "letters to knees" was the standard. This could certainly be preprogrammed in when the lineups were submitted and then updated in real time with a pinch hitter because they'd know the measurements of every roster member in advance.
Plus it would create jobs to update the software and input any pinch hitter info prior to the AB. The umpire would still be present to call foul/fair and close plays at the plate.
Is there a way to hide that forum? IE, many moons ago I had bookmarked the "unread posts" link which included an extra thing-a-ma-jig which made all the threads in the political forum hidden from view.
