Now's as good a time as any to get into the sweet sounds and lush arrangements of Philadelphia soul in the 1970s. 2011 marked the 40th anniversary of legendary writer/producers Kenneth Gamble and Leon Huff's creation of a label that set the groundwork for some of the best soul and R&B sounds of the decade, and this year's seeing a lot of excellent catalogue projects honoring that legacy.

We've already told you about Legacy's Golden Gate Groove: The Sound of Philadelphia Live in San Francisco 1973 (keep an eye out for a review from Joe!), and there are more great titles in store in the coming months as well. One of them is a stellar four-disc box set that combines the great arrangements of Philly soul with the ace mixing techniques of Tom Moulton.

Moulton, the father of the modern-day remix, is about as far from a stranger to Philadelphia International as you can get. In 1977, he mixed classic sides by The O'Jays, The Three Degrees, Harold Melvin & The Blue Notes and MFSB for the double album Philadelphia Classics. Over time, he was commissioned for a variety of other projects for the label, some of which never saw the light of day past a few rarer promo records or obscure compilations.

With the release of Philadelphia International Classics: The Tom Moulton Remixes, Harmless Records - a subsidiary of the U.K.'s Demon Music Group - has compiled all eight cuts from Philadelphia Classics and combined them with not only seven rare or unreleased vintage mixes, but another 15 extended versions commissioned just for this set. The Intruders, The Trammps, Billy Paul, Lou Rawls, Teddy Pendergrass - those are just a few of the artists ripe for rediscovery on this set. In addition to the four separately packaged discs, the box will also feature 16 pages of newly-written liner notes by acclaimed British music journalist Lloyd Bradley and rare photos of Moulton at work in Sigma Sound Studios, birthplace for countless classics of the label.

The box will be out February 27 in the U.K., and it can be yours to pre-order (for a rather stellar price, given the worth of the music) at Amazon after the jump.
