Catalyst for the swing era
On July 31, 1935, "King Porter Stomp" was released with "Sometimes I'm Happy" on the B-side, both arranged by Henderson and recorded on July 1. In Pittsburgh at the Stanley Theater some members of the audience danced in the aisles. But these arrangements had little impact on the tour until August 19 at McFadden's Ballroom in Oakland, California. Goodman and his band, which included trumpeter Bunny Berigan, drummer Gene Krupa, and singer Helen Ward were met by a large crowd of young dancers who cheered the music they had heard on Let's Dance. Newspaper columnist Herb Caen wrote, "from the first note, the place was in an uproar." One night later, at Pismo Beach, the show was a flop, and the band thought the overwhelming reception in Oakland had been a fluke.
The next night, August 21, 1935, at the Palomar Ballroom in Los Angeles, Goodman and his band began a three-week engagement. On top of the Let's Dance airplay, Al Jarvis had been playing Goodman's records on KFWB radio. Goodman started the evening with stock arrangements, but after an indifferent response, he began the second set with arrangements by Fletcher Henderson and Spud Murphy. According to Willard Alexander, the band's booking agent, Krupa said, "If we're gonna die, Benny, let's die playing our own thing." The crowd broke into cheers and applause. News reports spread word of the exciting music and enthusiastic dancing. The Palomar engagement was such a marked success that it is often described as the beginning of the swing era. According to Donald Clarke, "It is clear in retrospect that the Swing Era had been waiting to happen, but it was Goodman and his band that touched it off."
The reception of American swing was less enthusiastic in Europe. British author J. C. Squire filed a complaint with BBC Radio to demand it stop playing Goodman's music, which he called "an awful series of jungle noises which can hearten no man." Germany's Nazi party barred jazz from the radio, claiming it was part of a Jewish conspiracy to destroy the culture. Italy's fascist government banned the broadcast of any music composed or played by Jews which they said threatened "the flower of our race, the youth."
In November 1935, Goodman accepted an invitation to play in Chicago at the Joseph Urban Room at the Congress Hotel. His stay there was extended to six months, and his popularity was cemented by nationwide radio broadcasts over NBC affiliate stations. While in Chicago, the band recorded "If I Could Be with You (One Hour Tonight)", "Stompin' at the Savoy", and "Goody Goody". Goodman also played three concerts produced by Chicago socialite and jazz aficionado Helen Oakley. These "Rhythm Club" concerts at the Congress Hotel included sets in which Goodman and Krupa sat in with Fletcher Henderson's band, perhaps the first racially integrated big band appearing before a paying audience in the United States. Goodman and Krupa played in a trio with Teddy Wilson on piano. Both combinations were well received, and Wilson remained.
In his 1935–1936 radio broadcasts from Chicago, Goodman was introduced as the "Rajah of Rhythm". Slingerland Drum Company had been calling Krupa the "King of Swing" as part of a sales campaign, but shortly after Goodman and his crew left Chicago in May 1936 to spend the summer filming The Big Broadcast of 1937 in Hollywood, the title "King of Swing" was applied to Goodman by the media.
At the end of June 1936, Goodman went to Hollywood, where, on June 30, 1936, his band began CBS's Camel Caravan, its third and (according to Connor and Hicks) its greatest sponsored radio show, co-starring Goodman and his former boss Nathaniel Shilkret. By spring 1936, Fletcher Henderson was writing arrangements for Goodman's band.
