Summertime swelter meets sassy belters when an all-star lineup of blues women take the outdoor lawn stage for a backyard barbecue this weekend. From her early years in Mother Earth up to her recent solo work, Tracy Nelson is a force to be reckoned with, and no one is likely to forget the deep roots that run in Carlene Carter’s blood as the descendant of America’s most famous country-music family. Dorothy Morrison’s star turn in the Edwin Hawkins Singers’ “Oh Happy Day” may have been the Texas singer’s best-known moment, although 1971’s seductive funk killer “Rain” is probably the hottest thing she’s ever recorded, and Annie Sampson and Angela Strehli round out the supergroup. Dave Gonzalez’s Stone River Boys open while the horseshoe pits clang away on Sunday, May 24, at Rancho Nicasio. Town Square, Nicasio. 4pm. $20. 415.662.2219.Gabe Meline
