The weekend's 6 best concerts: Feb. 23-25

Ani DiFranco @ First Avenue Ani DiFranco has managed to become one of the finest folk-based singer-songwriters of the last 30 years even with her total commitment to independence, from her '90s records all the way up to her 20th album, last year's Binary . Like all her albums, it was released on her own Righteous Babe label, and its standouts include the Obama tribute "Deferred Gratification" and the Justin Vernon-assisted "Zizzing."
