Did you catch Far*East Movement Monday (Feb. 7) night on "Conan" performing its Hot 100 top 10 hit "Rocketeer?" If so, then you may have wondered who was sitting in with the group on piano and subbing for the song's original guest vocalist, an absent Ryan Tedder. The fellow in question is British pop singer/songwriter Frankmusik, aka Vincent Frank, -- Far*East's Cherrytree Records labelmate.

In the U.S., Frankmusik is still likely best known -- so far -- as a friend to the Far*East, but he's a more familiar face in his U.K. homeland. His 2009 debut full-length album, "Complete Me," reached No. 15 on the Official Albums chart and spawned a pair of top 30 singles. After meeting up at one of Far*East's London shows last year, he says he and the group have become seemingly inseparable. "That evening we all went into the West End of London and enjoyed the delights that were on offer," Frankmusik tells Billboard.com. "Ever since that hazy night we have been friends since."

Frankmusik appears on the hip-pop act's "Free Wired" album (on the track "Fighting For Air") and guested on a "Jimmy Kimmel Live!" performance of "Rocketeer" last month. More recently, the two acts collaborated on a live rendition of "Rocketeer" -- co-written by Bruno Mars -- which was released to digital retailers. Of the latter, he muses, "[I'm] intrigued as to what Mars thought of me beat boxing, singing and playing his song on the piano. I doubt when he wrote it he would have ever expected a version quite like that from someone like me."

American fans may also know Frankmusik for his remixes of the likes of Nelly Furtado, Pet Shop Boys and Lady Gaga. Perhaps most famously, he reworked the latter's "Eh, Eh (Nothing Else I Can Say)" for her 2010 "The Remix" album, which debuted at No. 6 on the Billboard 200 and at No. 1 on Dance/Electronic Albums. "I produced the remix because of how much I loved the song," he says, noting what a "great pleasure" it was that his re-rub -- made two years before "The Remix" was released -- was good enough to make the cut for the album.

While he's enjoying visibility with the "Like a G6" group and his remixes for others, Frankmusik is also busy completing his second album, "Do It In The AM," due out in May or June in the U.S. The singer, who relocated from the U.K. to Los Angeles to record the set, says it's "a re-invention of my creative process. An answer to how committed I am to improve and finesse my craft. A transatlantic collaborative effort fueled by my need for personal change and soul searching from my move to L.A."

"Do It In The AM's" first single, the future-retro pop/dance cut "The Fear Inside," has notched 100,000 views on YouTube. "'The Fear Inside' is a song about relieving the pressures and complications of the modern world through the strength of a close and intimate relationship," he explains. "And it wasn't too bad getting to show that with Natalie Loren [the lead actress] in the video."

As for the meaning behind his upcoming album's title, Frankmusik says, "The AM was the time in which most of the body of work was created. Every sunrise of the past year meant much more than a new day. It felt like every day was a moment closer to remembering why I was making musik again."
