Although you may not be familiar with them, chances are that you have heard of their works. You might even be a fan.

Dr. Luke, Swizz Beatz, and Britney Spears have jointly produced hit songs and albums for Britney Spears and Ke$ha. DMXFlo Rida (Katy Perry) and Katy Perry (Flo Rida) are currently L.A.’s hottest record producers.

These mega-hits have been made possible by the Providence, R.I. doctor Lukasz Gottwald, who was born Lukasz Gottwald. “Party in the U.S.A”Miley Cyrus “Right Round”Flo Rida “Tik Tok”Ke$ha “I Kissed A Girl”Katy Perry

Also, Dr. Luke’s music is so infectious that it makes you want to wave your hands in air, tap your steering wheel, and crank up the volume on your radio.

If a radio hit is catchy, smelled like bubble gum pop, and annoyingly impossible to avoid, it was most likely produced by Dr. Luke.

Swizz Beatz, like Dr. Luke enjoys his success but still acknowledges that “people are fans of my music more than fans of me … because they don’t know who I am.”

This may be true, however, people know who he is and what company he works for.

Third album from Swizz Beatz “Haute Living,” released last summer, includes an eclectic mix of rock, hip-hop, and R&B stars such as Bono and Lenny Kravitz, Jay-Z and Kanye West and John Legend.

Beatz says that this album is a far cry form his first collaboration with hip-hop artist and current renaissanceman DMX.

They collaborated together in the late 1990s when X was part hip-hop’s notorious Ruff Ryders. Their aggressive sound led to multi-platinum success.

DMX’s famed legal issues have slowed down his music career. But X is now ready for more with Big Jake Music, an independent label. Beatz hasn’t forgotten about his friend of over a decade.

Beatz has recently produced X’s seventh studio album to underline his loyalty. “Undisputed,”It includes hip-hop heavy hitters like the late Notorious B.I.G. (aka Biggie Smalls).

Of DMX’s comeback attempt, Beatz said, “Expect the unexpected. Expect the new and improved. Expect hip-hop. Expect real music. Expect the Dog to be back.”
