Benny Goodman
He performed at the Palomar Ballroom in Los Angeles on August 21, 1935. Because of this show, he became known across the United States  His radio broadcasts from New York were too late at night for many people on the East Coast to hear them, but Goodman had many fans in California, and a very excited crowd greeted Goodman.  This got a lot of attention across the nation, and made the Goodman Band popular very fast. Some writers have said that this was the start of the Swing Era.
