    Jazz guitarist Joel Harrison came of age in 1960s and 70s' Washington, but he never saw it as a place to build a career as an adventurous, progressive musician. Everywhere he's gone, however, he's taken the sounds of the city with him.

''Growing up in that area allowed me access to a lot of different kinds of music,'' says Harrison, 61, who's now based in New York after living in Boston and San Francisco. ''Southern music traditions-old-time music, bluegrass, country as well as jazz and R&B.''

All of those appear to some degree in Free Country, a project Harrison began in 2003 as a means of filtering (渗透) country and bluegrass compositions through a up-to-date jazz sound and sensibility. On his new album, ''Angel Band: Free Country Vol.3, ''Harrison, on guitar and vocals (演唱), and his band take on many traditional bluegrass songs. Each cut is really kind of its own, distinct sound world. Since Harrison released the first two Free Country albums, he has produced 14 other albums. The Free Country releases, though, have been his most successful, and established his reputation.

In particular, Harrison drew inspiration from Danny Gatton, a D.C. guitar hero who similarly combines the local musical currents. Harrison was a self-described adorer of Gatton, going to attend his countless performances.

Harrison is also a composer. His work, rooted in progressive Jazz but exploring multiple types, is often through-composed and highly complex. He received a Guggenheim scholarship in2010 to compose and record an, eight-movement piece. The tunes he plays with Free Country are simpler, based on conventions of folk and pop music — which, for Harrison, is a large part of their appeal.

The music that he's covering timeless, and he aims to find endless currency in its timeless simplicity by maintaining me soul of the compositions and also adding a modern context and a modem language to it.
