Grassahol was the featured band during a recent happy hour at Byrne’s Pub. This high energy bluegrass band features Carl Yaffey on 3-finger and clawhammer banjo. In addition to being a musician, Yaffey is the author of several music-related books such as A Banjo Player’s Guide to Jammin’. Chas Williams, who plays both a mandolin and fiddle, writes many of their songs as well as providing a vocal lead or harmony. Buren Carter plays the guitar. Heidi White plays bass and does vocals. Listening to their music was a fun introduction to bluegrass.
