There are a few reasons for this:
* Limited involvement: While Bobby Martin was a talented musician and a member of the MFSB (Mother Father Sister Brother) house band, he wasn't a major songwriting or production collaborator with Gamble and Huff. His primary role was as a drummer and percussionist, contributing to the distinctive Philadelphia sound.
* Focus on artists and the sound: Gamble and Huff primarily focus on discussing their collaboration with the iconic artists they worked with at Philadelphia International, like The O'Jays, Harold Melvin and the Blue Notes, and the Stylistics. Their interviews often revolve around the creative process, songwriting techniques, and the impact of their label on the music industry.
* Shifting focus over time: As time has passed, the focus of the conversation about Philadelphia International Records has shifted towards the legacy of the label and the influence of its sound on contemporary music. This leads to more discussions about the overall impact of the label and the artists associated with it rather than specific individuals.
It's important to remember that Bobby Martin was a crucial part of the Philadelphia International Records sound. He provided the rhythmic foundation for countless hits, playing on iconic tracks like "Love Train" and "TSOP." His skills and contributions are undeniably important to the history of the label.
However, in terms of public discussion, Gamble and Huff typically focus on the broader picture of their achievements and the artists they worked with. This doesn't diminish Martin's contribution, but simply reflects the primary focus of conversations about Philadelphia International Records.
