question:
The title of this video mentions Argentine Tango. Unfortunately, what is being taught on this tape is not authentic Argentine Tango. Not even close. It's ballroom tango. There is a huge difference: in music, style, steps, posture, etc... Don't be fooled by ballroom instructors trying to teach Argentine Tango. The only authentic instruction available on the market comes from authentic Argentine instructors from Buenos Aires.
answer:
Negative

question:
It is curious that one one the more significant achievements of "Pastor" Charles Taze Russell is omitted above. That fact is that he was the primary founder of the Watchtower Bible and Tract Society, and the religion now known as "Jehovah's Witnesses." No small amount of his theology is controversial in the body of the Church as a whole, as it would be (for different reasons, perhaps) amongst Jehovah's Witnesses.
answer:
Negative

question:
It's about time that stoner rock acknowledged it's british blues/blues-rock/psychedelic/acid rock/hard rock roots. Good riffs, nice bluesey vocals, that's all I gotta say.
