4Minute has accomplished a feat that no other K-Pop girl group has been able to do thus far.

The idol group held their "4Minute Fan Bash in Barcelona 2014" concert at Club Razzmatazz on May 23.

This was a special moment for the group as it was their first solo concert in Europe.

The members sang their debut song, "Hot Issue," and passed the mic to the crowd to sing along to their music. 4Minute performed for 2 hours and 30 minutes and had a blast finally meeting and communicating with their fans in Europe.

The girls previously held a concert in Stockholm as well on May 25. "4Minute Fan Bash in Stockholm 2014" was a small-scale showcase held at the Debaser Medis in the country's capital, attracting around 1,000 fans across Europe, including Norway, Finland, France, Germany and Italy, according to the Korea Herald.

4Minute performed their hit songs "What's Your Name," "Mirror Mirror," "Muzik," "Heart to Heart," "Hot Issue," "Volume Up" and more.

The girls recently got together with Dazed and opened up about their music video concepts and comeback plans.

When asked what the biggest challenges of making their most recent mini-album "4minute World" were, each of the girls gave honest answers regarding their hardships.

"There was a time I had to record by myself because of the schedule in movie shooting. That was one lonely recording session," stated Jihyun.

"Among all the challenges, it was the wardrobe as I was styling the group. The 2014 S/S pieces were hard to get in and out of Korea," said Gayoon.

Sohyun added, "It was fun making the album but it was a bit upsetting that we couldn't appear on many TV shows."

"I think there was some difficulty along the line of self-development," continued Jiyoon.

Unlike the other members of the group, HyunA explained that she didn't have any challenges because of the group's daily meetings.
