The time of flooding idols has come. It does become confusing when so many groups come out everyday. What the idols need in such an environment is the 'different from others' factor, and there are those who have arrived at the solution of 'visiting marketing.'

Ever heard of the term 'busking'? Performing on the street in order to solicit money from passersby has long been the territory of the indie artist. Commercial artists hardly had a reason to do street performances when it would take time away from their busy schedules.

But the mood has changed. Idols who are considered 'the icons of commercial music' have started busking. The logic is that the only way to gain longevity is to build a rapport with fans instead of looking at the 'money in front of their eyes.'

These idols approach the fans with a familiarity of neighbors as opposed to celebrities. They unfold their talent and wit on the street outside of TV and the stage with a 'one step closer' strategy.

The most recent group with active street performances is Girl's Day, the group behind the popular song 'Female President.' In addition to public appearances, they are touring the country with 'guerrila concerts.' The mindset is to go back to the time of their debut, to remember their origin.

The group held a surprise performance at 9pm in Busan's Haeundae on the 29th and built a rapport with citizens who had come out to enjoy the summer night. The guerrila concert drew approximately 3000 fans.

In order to visit Busan, the group had created a schedule down to the minute. After finishing their live performance on MBC 'Music Central,' they got on the plane towards Pusan, and after the performance, immediately headed back to Seoul for a performance on SBS 'Inkigayo.' It's an attitude of dispensing with rest in order to be with their fans.

During the 30-minute performance, Girl's Day expressed their regret to the fans: "We're sad that we have to leave for Seoul right away for our show in the midst of the excitement. We're sorry to our fans in Busan that we can't stay longer. Next time we visit, we'll show you an even better version of ourselves."

A male idol group that thrives on meeting with their fans is the new Boy's Republic. The five members have long participated in events with fans even before their debut, and have established themselves as the new 'trendy group.'

After releasing 'Party Rock' on the 5th last month, the group have been holding various guerrila events in places like Hongdae, Myungdong, Bupyong, building a friendly image.

And it's not just the meet-and-greet. Boy's Republic prepared ttukboki for female students and distributed candy on White Day, gaining the nickname 'Next Door Idols'.

Boy's Republic manager Park Byung Chang of Happy Tribe revealed: "It's more meaningful to come out of the TV to communicate directly with the fans. They'll continue to hold spontaneous events as long as their schedule allows for it."

Idol groups move swiftly without rest. Today, they continue to break a sweat in order to survive in the harsh world of entertainment.
