Brown Eyed Girls have made their long-awaited comeback to the K-pop scene with the release of two music videos.

The four-member girl group finally released their sixth album, "Basic," after a hiatus of 2 years and 4 months. The album is led by double title tracks "Brave New World" and "Warm Hole."

"Brave New World" sports a futuristic music video that shows the four members traveling to various exotic locales to uncover the secrets of the universe. In a recent interview, the members stated that the video is about, "looking back at the 20th and 21st century as someone who lives in the year 3000." The song was been influenced by music from the 1980s up to now.

The music video for "Warm Hole" was also released. As expected from the racy title, 'Warm Hole' contains a multitude of sexual themes and innuendos throughout, including the girls being dressed up in outfits that resemble playboy bunny costumes.

Brown Eyed Girls will hold their first live stage on November 5th on M! Countdown.
