From time to time there are songs that you find on YouTube that are truly spectacular songs, by large groups, but that collect all their value, or at least much of it in that they are recorded in concert, so the groups always shine a lot plus; and they reveal the great variety of their subjects as well as many times the great quality of them as musicians to improvise.
One of this videos to my liking, of a song that is a great theme is Californication, by the Red Hot Chili Peppers. This song was recorded live at a concert at the Slane Castle. Just enjoy this great song and its wonderful 3-minute guitar lead.
