the Hollywood area of Los Angeles, California.

The Hollywood Bowl is a modern amphitheater (like the Greek amphitheaters but...bigger) and is located in the Hollywood area of Los Angeles, California. 
It also just so happens to be the largest amphitheater in the country and can sit 18,000 people for any music performance. But, my guess is that most people don't even go for the show; the go for the drive to the theater. The road leading up to the amphitheater is shaped like a musical note. Coincidence? I think not!

You can see blue, red, yellow, green and even pink houses there, but the Island's citizens can't choose the colours - government selects them itself.
