Allmusic music critic Thom Jurek praised the album and wrote the recording "proves something beyond their well-founded reputation as a live unit: that they can write, perform, and produce great songs that capture the authentic, emotional fire and original arrangements that so many modern blues and roots recordings lack... Revelator is a roots record that sets a modern standard even as it draws its inspiration from the past. It's got everything a listener could want: grit, groove, raw, spiritual emotion, and expert-level musical truth."[2] David Fricke of Rolling Stone wrote "[Trucks] and Tedeschi, a perfect vocal foil, now front the best Dixie-funk family band since Delaney and Bonnie Bramlett."[3]
