BOYNEXTDOOR has decided to add an extra concert on July 31st for their first world tour 'KNOCK ON Vol.2' in Busan. The performances at Sajik Indoor Gymnasium, previously scheduled from July 31st to August 2nd, will now be expanded to three sessions. All tickets from the general pre-sale on July 1st were sold out, leading to the decision to add another show due to overwhelming fan support. Pre-sales for the new July 31st concert will begin at 8 PM on August 8th. This expansion brings the 'KNOCK ON Vol.2' world tour to a total of 24 cities and 35 performances, spanning from Seoul and Busan to six cities in Japan, ten in North America, and six across Asia. BOYNEXTDOOR has showcased exceptional vocal abilities and improved performance skills through their recently released debut album 'HOME,' with their title track 'VIRAL' entering Melon's monthly chart and being adopted as the official cheering song for the LG Twins baseball team.
