Reviews of "Brothers and Sisters" in 1973 were mostly positive. Bud Scoppa of "Rolling Stone" deemed the album "no masterpiece, but the new band has shown that it can carry on the work of the old, and add the appropriate new twists when necessary. They've finally discovered a form that feels as natural in the studio as it does in front of their people. It's heartening to see a group of this commercial and critical stature still working so hard at getting even better." Janis Schacht of "Circus" was very positive, writing, "Never, even in the face of adversity, do the Allman Brothers quit making strong, hard-driving rock/blues albums. ... This is another in the continuing line of quality products from The Allman Brothers Band." "Billboard" called it "A fine blues/rock set from this fine band, featuring top lead vocals from Gregg Allman and Dickey Betts, and the excellent instrumental fusion for which they are particularly well known." In "Creem", Robert Christgau said "Gregg Allman is a predictable singer who never has an unpredictable lyric to work with anyway, and the jams do roll on, but at their best—"Ramblin' Man," a miraculous revitalization of rock's weariest conceit—they just may be the best."
