Singer Psy became the reason why the streets of Hongdae became congested, as he held a highly successful Guerilla concert there on the evening of November 4th. After a 4-year hiatus from the music scene, Psy returned with his 5th full-length album 'PSYFIVE' and broke the 10,000 album sales mark! The singer announced on the 4th through his me2day that he will be holding a Guerilla concert in Hongdae to commemorate the special moment. Reportedly, over 5000 fans gathered to see the eccentric performer, even under such short notice. Psy uploaded a photo from his successful concert with the caption, "A moment when we were moved by one another." Fans who saw the picture commented, "The emotions from last night are rising back up", "Psy's concerts are always exciting", "My first time ever attending a concert like that", "Concerts are always a must! Hoorah to adult idols!" Psy performed his hot title track, 'Right Now', and delivered eight songs in total (including two tracks for an encore performance). Source: Chosun Photo: Psy's me2day
