Love them or hate them, but The Carpenters where the greatest pop band of the 70's, (sorry Abba and Jackson 5 fans).

Lead singer and sometimes drummer Karen Carpenter passed away from anorexia in the early 80's, but her brother Richard is now paying tribute.

With the latest technology, Richard has a concert planned where he plays live, while videos of his sister singing play on the big screens and maybe even (wait for it) holograms.

This has been done before with Elvis and Nat King Cole, but the word is this is far more advanced from those early versions.

Maybe Richard can set up a duet with Karen and Tupac?
