Ten years into his role as poster boy for pop soul and peak-hour R&B, Syl Johnson did an unlikely about-face and cut the most inspiring and powerful song he'd ever touch.

Issued on 45 in September of 1969, "Is It Because I'm Black" struck an immediate chord within the black community, forcing the song up the charts by sheer volume of call-in requests.

It would be Syl's biggest hit for Twinight, climbing as high as #11 on the Billboard R&B chart during its 14-week stay, marking the defining moment of what had become more than just an occupation.

Syl had his hands on a career and worked tirelessly rehearsing his next opus, an album of songs reflective of the changing times.

With "Is It Because I'm Black" still bolding the pages of Billboard, the coming LP's title appeared to Syl plain as day _ or, in this case, black as night.

Issued in April 1970 _ a full 13 months before Marvin Gaye's What's Going On _ Is It Because I'm Black can rightly be called the first black concept album, a distinction few give it credit for.

But that factoid, whatever its meaning then or now, failed to inspire music buyers: Johnson's record never got a whiff of the two million copies Gaye's did in its first year of availability.

Syl lays the blame squarely on the record's lack of marketability to a white audience. The album's cover didn't exactly move units either.

Photographer Jerry Griffith dragged Syl to a burned-out building on 43rd Street to shoot the back cover image, and he finger-painted the iconic title over a stock photo of an eroding brick wall.

The title track, coupled with the politically charged "I'm Talking About Freedom" and ghetto conscious "Concrete Reservation" sealed the album's cool reception as the work of an "angry black man." Which is unfortunate, as "Together Forever," "Come Together," and "Black Balloons" are positively uplifting, forming their own pot of gold at the end of a grayscale rainbow.

The album's closer burns the brightest. "Right On" devolves into a full-on party track, ending with Syl riffing on the line "I'm gonna keep on doing my thing," as if to answer his critics before their needles reached the run-out groove.
