The Great Otis Redding Sings Soul Ballads, simply referred to as Soul Ballads or Sings Soul Ballads, is the second studio album by American soul singer-songwriter Otis Redding, released in 1965. The album was one of the first issued by Volt Records, a sub-label of Stax Records, and Redding's first on the new label. Like Redding's debut Pain in My Heart (1964), Soul Ballads features both soul classics and originals written by Redding and other Stax Records recording artists. The recording sessions took place at the Stax studios in Memphis. The album features a stereo mix made by engineer Tom Dowd, replacing the early mono mix. The album features the Booker T. & the M.G.'s, the horn section Memphis Horns and the pianist Isaac Hayes, who possibly first appeared on this album, although this is disputed, as he was not credited on the liner notes. Unlike Redding's debut album, Sings Soul Ballads was released both on Atlantic's subsidiary Atco Records and Stax's Volt Records. While the album and its singles were moderately successful on the music charts, it includes Redding's first top-10 single, "Mr. Pitiful". The album received mixed critical reception. Recording The recording session took place at the Stax studios in Memphis. Guitarist Steve Cropper and Stax producer Jim Stewart both agreed with engineer Tom Dowd's decision to install a two-track recorder during the recording of "Mr. Pitiful". The stereo four-input Ampex mixer is used throughout the album, which means that the instrumentation is either in one channel or the other, but the vocals and echo are in only one channel. This is different for mono recordings, where only one channel is used. Sings Soul Ballads features Booker T. & the M.G.'s organist Booker T. Jones, pianist/guitarist Steve Cropper, bassist Donald "Duck" Dunn, drummer Al Jackson, Jr., and the Memphis Horns, consisting of trumpeter Wayne Jackson, tenor saxophonist Charles "Packy" Axton and baritone saxophonist Floyd Newman. The album contains 12 songs, the majority of which are, as the album's name implies, soul ballads. The album opens with "That's How Strong My Love Is". Written by Roosevelt Jamison and altered by Cropper, the song was first performed by O. V. Wright on Goldwax Records, where it was cut by both Jamison and Wright. Redding's version was released days after the original. The Rolling Stones covered the song shortly afterwards and included it on their album Out of Our Heads (released
