Critical listening and altered states

Ok, this is not a question about relaxing, but about listening to evaluate how the system (or a piece of gear is sounding).

What, in your experience, are the pluses and minuses of altering your state of mind for listening? This can include anything you've used to affect your everyday state of mind, from coffee, beer, scotch, tobacco, to much stronger — and psychoactive, dissociative — additives.

What do you gain by altering your consciousness in terms of what you notice, attend to, linger on, etc?
What causes more details to emerge?
What allows you to stick with a thread or, alternately, make new connections?

Or perhaps you like to keep all those things *out* of your listening; if that's you, please say a bit about why.

It's simple, if there is ONE person locked up behind VICE, that's one to many.

When child molesters, rapist, murders, thieves, and ARSONIST, roam the country freely and someone who grew pot, or paid for a sex worker or bought dope from a COP is in jail.. IT'S BROKE.. Cowards laws for cowards..

The only problem with Vice is the corrupt COPS that work it.. Everyone is dirty.. That's the reason they work it.. I never met one that wasn't either..

I worked for Laidlaw, huge contract for cleaning labs, pot farms, you name it.. The people watching US.. Keep your wives and children locked up.

NEVER turn your back and lock your tool boxes around them... Worst thieves I ever met. 

Every one bragged about what they stole from the raid sites.. OPENLY...

25-35 years ago.. DEA, ATF, my A$$. More people murdered than the flippin' Taliban behind no knock warrants..

Flash bangs are HAND GRENADES, you should see what happens to babies and animals... OPS!!! Wrong house.. Nothing found.. 

Prison and NO TRIAL.. Hand grenades on the American public and death squad warrants. Never see a court.. Hand them over the families..

And then defend their action.. An American dies someone goes to jail..

A search warrant is a tool used to conduct a reasonable search, it's not a death warrant.. It's always some 25 year old without a conscience, that's why they use the YOUNG.. They haven't grown from a Barny to an Andy, add 15 years..

You get Andy..20% of the time.. A peace officer with sense. Not one bullet Barney 80%.. I have a family FULL of good cops.. thank God.. Maybe one bad one or two, well there might be 1/2 dozen or so.. Well actually they are all dirty.. They just didn't get caught..

One good one for sure out of 15 or so.. Not bad.. I think it's because he's Swedish and married into the family.. :-)

I used to occasionally love listening to music live or at home after taking LSD, mushrooms, mescaline, or smoking a bit of weed.  Works really well with immersive music.
