With modern day tools and technology taking over, it's nice to see at least somethings are still kept in their original form. This video, which is a series of videos with other bands (America, Roxy Music, etc.), shows  T. Rex in the form that they were in before Tanx, Zinc Alloy, and the super  stardom. And, I must say, I like the earlier version of T. Rex better. No  cocaine, no arguments, no greed. Just straightforward music. "Life's A  Gas", "Twentieth Century Boy" (Featuring the outfit worn by  Marc that led to Ziggy Stardust), "Jeepster", and "Ride A  White Swan" are all great versions. Don't be keen to buy this just  because it's only 20 minutes long. It's the best 20 minutes of live music  you'll ever hear!
