1:56 PM PT -- Biz Markie's celebration of life is just now wrapping up, and as expected ... it was an emotional ordeal, especially when the man's widow stepped to the podium.
Tara Davis delivered some heartfelt remarks during the memorial, and actually made a stunning revelation about who sent her condolences in the wake of Biz's death -- none other than the Obamas themselves wrote a letter expressing their sorrow, she says.
That truly speaks to Biz's impact and reach -- the former President and First Lady felt compelled to send thoughts and prayers to Tara ... pretty incredible, really.
His kids also spoke ... and expressed solemn remembrances, saying how much they'd miss him. All around powerful stuff -- but the Obama news might just be the headline.
Biz Markie is being honored in the wake of his death -- with friends, family and loved ones coming out to speak on his behalf in a major celebration of life ... and TMZ's live streaming the event.
The rapper's funeral took place early Monday in the Big Apple, with a public memorial service to follow ... which you can watch in full here.
Al Sharpton is set to deliver the eulogy -- and other MCs are also expected to be on hand during the proceedings ... including Fat Joe, LL Cool J, Papoose, Big Daddy Kane, Al B. Sure!, Leland Robinson, among others. It's unclear if any of them will actually deliver remarks.
Word is ... Biz will be dressed to the nines, courtesy of the Harlem fashion designer, Dapper Dan.
It's sure to be an emotional moment for New Yorkers and hip-hop fans alike -- as you know, BM was a trailblazer in the genre ... and was loved by many before his untimely death.
