Yola is all about taking a stand — hence the title of her just-released second album, “Stand for Myself” — but she also delivers quite a wallop even from a seated position. The formidable singer-songwriter is joined by her band for a slightly stripped-back, sit-down performance of four songs from the new Dan Auerbach-produced release. Yola also takes viewers on a tour of what she considers her own musical den: Auerbach’s Easy Eye Sound studio in Nashville.
