Mae The Philly Sound yn dogfennu'r cyfnod amser rhyfeddol a esgeuluswyd yn aml yn hanes cerddoriaeth Philadelphia o'r 1960au i'r 1980au cynnar a ddylanwadodd ar gerddoriaeth bop a diwylliant America. O Chubby Checker i Lou Rawls, denwyd artistiaid o bob cwr o’r byd i Sigma Sound Studios Philadelphia yn y gobaith o ddal llinyn sain newydd yn dod o stiwdio gychwyn a sefydlwyd gan beiriannydd Philadelphia anhysbys. Byddai hyn yn cynnwys The O’Jays, The Delfonics, Teddy Pendergrass, David Bowie, Elton John, Dusty Springfield, Stevie Wonder, Billy Joel a John Legend. Yn ei oes fwyaf dylanwadol, gosododd y gerddoriaeth o Philadelphia y bont i bobl o gefndiroedd amrywiol gydweithio i greu cyfnod annileadwy mewn cerddoriaeth. O fewn muriau Sigma Sound yr unig beth oedd yn bwysig oedd pe baech chi'n gallu chwarae a phe gallech chi, roeddech chi i mewn. Wedi'i gynhyrchu a'i gyfarwyddo gan gyn-fyfyriwr Sigma Sound, mae mynediad i'r prif artistiaid, cynhyrchwyr a pheirianwyr yn ddigynsail gyda ffilmio'n digwydd ar draws yr Unol Daleithiau a'r Deyrnas Unedig.
The Philly Sound documents the amazing and often neglected time period in Philadelphia music history from the 1960's to the early 1980's that influenced both pop music and American culture. From Chubby Checker to Lou Rawls, artists from all over the globe were drawn to Philadelphia’s Sigma Sound Studios in hope of capturing a new strand of sound coming from a startup studio founded by an unknown Philadelphia engineer. This would include the likes of The O’Jays, The Delfonics, Teddy Pendergrass, David Bowie, Elton John, Dusty Springfield, Stevie Wonder, Billy Joel and John Legend. In its most influential era, the music from Philadelphia laid the bridge for people from diverse backgrounds to work together to create an indelible era in music. Within the walls of Sigma Sound the only thing that mattered was if you could play and if you could, you were in. Produced and Directed by Sigma Sound alumnus, the access to the major artists, producers and engineers is unprecedented with filming taking place across the US and United Kingdom.
