BEAST has only been making progress in the K-pop world since their debut back in 2009.

The six-member idol group wrapped up promotions for "Good Luck" and hosted an unplugged concert for fans as a way to show their gratitude for their ongoing support.

The "BEAST Unplugged Concert" was held at Melon Ax Hall in Seoul on July 27. BEAST opened the stage with "Lightless," singing "Midnight," "I'm Sorry," "The Fact," "Fiction," and "Dream Girl" live.

The idol group also sang six songs that fans requested and further thanked those who attended the concert with special gifts. 500 fans were selected to attend the band's recent solo concert from a pool of 10,000 fans that had sent in applications to get tickets, according to Yahoo Entertainment Singapore.

BEAST took home 12 trophies with their single "Good Luck" while their sixth mini-album took the No. 1 spot on monthly music charts.

"Good Luck" was also featured on Billboard for its ability to blend different genres by "mixing high-electro beats with traditional classical music."

"The most striking part about 'Good Luck' is its production that pairs classical music elements like dramatic, orchestral strings and piano melodies with soaring synths and fizzy electronic pops," wrote the music magazine, explaining why the single has become so successful.

The music video also contributed to the recent success of "Good Luck," with the boys wearing soccer-player socks in the dance sequences.

BEAST has been able to stand out as a K-pop act because of their unique musical taste, which they explained during their interview with Today's Zaman.

"Our music is actually a blend of many different styles. And this diversity also stands for the [genre called] K-pop. We can say that we basically focused on dance music and electronic music on our newest album. Most of our songs feature elements of R&B and dance music. But in short, despite all the various elements that make up our music, we can say what we make [are] 'cheerful pop songs,'" stated the members of BEAST.
