Rookie girl group MAMAMOO's superior live singing skills were proven.

A MR-removed clip of MAMAMOO's performance of "Mr. Ambiguous" was posted on an online community blog.

In the clip, MAMAMOO shows an unwavering stability despite the choreography. Toward the end of the performance, the members sing in harmony.

Internet users claimed: "Skilled girl group!", "Their dance, singing, and appearance are all perfect", and "Their live singing is better than the CD!".
