An attendee of a David Grisman Quintet show is going to hear a world of different musical genres and sounds, the quintet’s publicist Rob Bleetstein said.

After all, why would the mandolinist want to change the blend of swing, bluegrass, Latin, jazz and Gypsy music he has been crafting for nearly 40 years?

The current and longest running version of the DGQ will bring its polished, original sound to the Georgia Theatre tonight in support of the group’s summer release “Dawg Nation.”

Grisman’s unique style was so inventive that he branded it “dawg” music.

With humble beginnings as a young player in New Jersey and then in the growing New York folk scene, Grisman since has recorded with the likes of the Grateful Dead, Bela Fleck, Stephane Grappelli and James Taylor, to name a few.

During the late 1960s, he — along with fellow bluegrass players such as Vassar Clemments and Jerry Garcia — began composing original music for their group, Old & in the Way.

Recently, he rejoined surviving Old & in the Way bandmates Vassar Clements and Peter Rowan and added Herb Peterson and Bryn Bright to record an album.

The creatively-titled “Old & in the Gray” is a continuation of the bluegrass and contemporary material the group once mastered.

Since its birth 26 years ago, however, the DGQ has made its way to the forefront of major jazz, folk and bluegrass festivals around the globe.

The group has been touring the country following the completion of the summer Jamgrass Tour, in which they shared the bill with Sam Bush and Yonder Mountain String Band.

The DGQ’s current lineup includes bassist Jim Kerwin, multi-instrumentalist Joe Craven, floutist Matt Eakle and guitarist Enrique Coria.

“The addition of Enrique to the group has brought more Latin influence to the music,” Bleetstein said.

In 1990, after bouncing around major labels for most of his career, Grisman founded his own record label, Acoustic Disc. Since then, the label has released more than 50 recordings, all under the production of the man himself.
