Call him musically promiscuous – because Edgar Meyer certainly plays around.

Indeed, the double-bass player with the fearsome chops has played with just about everyone – the Indigo Girls and T-Bone Burnett, Lyle Lovett and Yo-Yo Ma.

No one crosses over quite as much as he does, from bluegrass to jazz to classical and back again.

Catch him tomorrow at a free concert at Town Hall, when he and pianist Amy Dorfman take on Vivaldi, Chopin, Bach – and Edgar Meyer (he composes, too).

“I grew up in classical music, but I don’t partition music off that neatly,” he told The Post the other day from his home in Nashville.

“My father was a jazz player, but he taught orchestra and loved be-bop.” His father also played the double bass, which is why Edgar started playing it too – at age 5.

“It was never about the sound,” he says, simply. “It was all about my dad.”

Free tickets for Sunday’s 5 p.m. concert will be available at the Town Hall box office, 123 W. 43rd St., between Broadway and Sixth Avenue, beginning at noon.
