Intensive care may be necessary

Charlemagne Palestine, known in music circles for his marathon all-night concerts in the 1970s (they were often so intense that he bled on the keys) is returning to the Los Angeles stage tonight after an 11-year absence. As part of the Monday Evening Concerts series, he will perform one of his seminal works, “Schlingen-Blängen,” on one of the world’s largest church pipe organs at the First Congregational Church.
