The Mauch Chunk Opera House, 14 W. Broadway in Jim Thorpe, will present its first ever Hump Day Party this evening at 7:30 with a free concert featuring the music of Front Country.

In the last few years, the band has performed at numerous bluegrass festivals and has supported Steep Canyon Rangers, Leftover Salmon and Greensky Bluegrass.

What started as a group of friends playing bluegrass in San Francisco’s Mission District has morphed into a touring powerhouse of song and sound, transcending their humble string-band roots.

Front Country’s dynamic instrumental textures take flight with grace and gravitas while rooted in the relentlessly soulful vocals of lead singer-songwriter Melody Walker. Along with mandolinist Adam Roszkiewicz, guitarist Jacob Groopman, violinist Leif Karlstrom and bassist Jeremy Darrow, this quintet has been called “passionately intoxicating” and “orchestral” and Walker’s bluesy vocals have been described as “rafter-shaking.”
