Question: Title: THIS IS A REAL BOOK ON TAI CHI CHUAN! Review: There're lots of "New Age Tai Chi Crap"out there. This is one of the "rare" books that deals with what Tai Chi Chuan is: A MARTIAL ART!. Chen Pan Ling was one of the finest "old guard" MASTERS of the Internal Arts. He is the ONLY disciple of Yang Shao Hou (His brother Yang Cheng Fu changed the original form into an smooth EXERCISE taking away every martial aspect like Fa-jing and Dim Mak) who was skilled in the real Yang Lu Chan's Tai Chi. I'm fed up of coming accross with fake masters and "soft and sweet" Tai Chi materials. The real Tai Chi CHUAN (Fist) is a devastating martial art that requires hard practice. In the West, only Mr. Erle Montaigue (you like it or not) keeps the Internal and Martial Tai Chi way. If you want to have a book on REAL TAI CHI CHUAN this is THE ONE.

Question: Title: Is The Title Song A Satire? Or Is It Serious? Review: Another reviewer wrote that he could not believe that Cristian was serious about the title song when he saw the video for it. I haven't seen the video, but I had the same thought when I heard the title song, "Azul." This song has every single cliche of the 1980s power pop sound. And I do mean EVERY single cliche! It is really amazing to hear all of those cliches in one song, especially one that was NOT produced in the 1980s. That's why I think that this song and its musical arrangement might be a satire of 1980s American pop music. Either that, or Cristian loved that style of music when he was growing up (he was a child and teenager in the 1980s) and decided that he wanted to record a song that had that particular sound. The musical arrangement is so different from everything else on the album that it just doesn't seem possible that this was done seriously. I think it's either satire, or just a fun and silly thing Cristian wanted to do. Does this product review convey a negative or positive sentiment?
