Veteran Japanese rockers Mr. Children attracted so many fans to this year¡¯s edition of the Summer Sonic music festival that they made Smashing Pumpkins¡¯ frontman Billy Corgan upset.

¡°Thank-you for the warm reception,¡± he said sarcastically in Osaka on Saturday, in response to the legions of Mr. Children fans who crowded the area just ahead of the Japanese group¡¯s set. Ah, the trials of being an opening act.

Despite Corgan¡¯s rage, Mr. Children¡¯s supporters were one of the reasons the 14th Summer Sonic, held simultaneously in Chiba (representing Tokyo) and Osaka, sold out both legs of the event (as well as the pre-festival SonicMania night) for the first time ever. The festival¡¯s decision to cater to the disparate fandoms of hard rock and J-pop made this happen, and resulted in some of the most impressive crowds Summer Sonic has ever seen.
