Bluegrass

Since forming in 2006, The High 48s have been making music that
combines the soulful sound of classic bluegrass with a modern
attitude, original songs and a wide range of influences far beyond
Bill Monroe, the Stanley Brothers, and Flatt and Scruggs. In a genre
created and dominated by artists from the South, The High 48s were
born and raised in the Upper Midwest. And in a music scene where
playing standards is the norm, The High 48s are a band of
songwriters who perform their own material in addition to the
“festival favorites.” They return to Oak Center for another
entertaining, high-energy show.
