Lawrence Krauss is a theoretical physicist, the Foundation Professor of the School of Earth and Space Exploration and director of the Origins Project at the Arizona State University (that's a long title). He was one of the earliest contributors to the theory that the universe is flat and in order for a flat universe to exist, the universe has to be dominated by dark energy.
Apart from being a distinguished physicist, he is also a popular science communicator. He has written a number of bestselling popular science books like The Physics of Star Trek, A Universe from Nothing and Quantum Man: Richard Feynman's Life in Science.
He is a no-nonsense person and his talks are extremely interesting. His sarcasm added to his dry sense of humor makes these talks entertaining. He is an atheist and a critic of string theory which means that you could hear a number of subtle attacks on religion and string theorists. Some of his talks are for the general audience while others are for people who are interested in more details. His talks have overlapping topics but each one of them have their own unique theme. Here are links to some of his talks
1. His talk during the Origins Symposium which includes the most common topics that he usually talks about - dark matter, dark energy and our place in the universe. This is an excellent talk and I would say that if you want to understand the basics of some of the most complicated topics in physics, like the ones mentioned above, this is the talk you should listen to. (If you are interested in understanding the theory, I have posted the links to lectures by Sean Carroll in this post).
2. A cosmic mystery story - This is a talk on atoms, which he starts with description of the Big Bang and ends it by describing the end of the universe, with special emphasis to evolution of life on Earth. This was talk that he gave at Fermilab in 2001.
3. Quantum Man: Richard Feynman's Life in Science - This is a talk based on his book by the same title, organized by the science network. You will want to buy his book after you listen to the talk.
4. One his recent talks titled "Cosmic connections" where he talks about our relationship to the universe. This is a casual talk which could be enjoyed by everyone.
5. In this Science and Religion Lecture, he explains why Intelligent Design is not a scientific theory and why it should never be taught at school.
Apart from these talks, there are a few discussions that Lawrence Krauss has been a part of. Here are links to two of the discussions that I enjoyed.
1. Brian Greene and Lawrence Krauss discuss string theory and the theories of everything
2. A panel discussion moderated by Phil Plait at TAM 2011. The panel consists of Bill Nye, Neil deGrasse Tyson, Pamela Gay and Lawrence Krauss. All are science communicators but by the end of the talk you would see that Lawrence puts up the best show.
If you like popular science lectures, then you shouldn't miss these talks.
