The Ossipee Valley Music Festival is showcasing 20 bands on four stages over four days this weekend, bringing a variety of roots music to a quiet corner of southern Maine.

Now in its 16th year, the music festival, held at the Ossipee Valley Fairgrounds in Hiram, has grown to include workshops in guitar and fiddle playing, songwriting and harmony singing.

Also, an instructional program for children called Roots & Sprouts Music Academy teaches children fiddle, guitar, banjo and mandolin playing and culminates in a performance on stage Sunday morning. New this year is a farm-to-table brunch held on Sunday during performances by three bands.
