Live music by a lake is a kind of summertime entertainment ideal. And, for those who live in Lakeport, it’s not hard to find, thanks to the KXBX 98.3 FM free Friday concert series at Library Park in Lakeport. On August 6, Keep on Truckin’ will offer a Woodstock tribute; on August 13, the Fargo Brothers will play rhythm and blues; and on August 20, In the Led will deliver Led Zeppelin tunes. Shows start at 6:30 p.m.; bring low-back chairs and blankets. Free music-by-the-water is also on tap at Clearlake’s Austin Park, where, on August 7 at 6 p.m., Rockin’ Down the Hiway will play the music of the Doobie Brothers and the Steve Miller Band.
