By early 1969, the original line-up of Pearls Before Swine - which had only ever performed in the studio, never live - was disintegrating around its leader and mainstay, singer and songwriter Tom Rapp. Original members Lane Lederer and Roger Crissinger had left, and Rapp had married Dutch traveller Elisabeth (surname unrecorded), whom he had met in New York when recording the album Balaklava. Original member Wayne Harley remained in the group, but left shortly after These Things Too was recorded.
The group had now left ESP-Disk and joined Reprise, a major label, and Rapp and producer Richard Alderson recruited studio musicians to play on the album. Chief among these was Jim Fairs, formerly of garage band The Cryan' Shames, who acted as co-producer and arranger as well as musician. Other musicians included violinist Richard Greene, later of Seatrain, and jazz drummer Grady Tate.
These Things Too has been described as Rapp's "dreamy" album, and it is generally less well regarded by critics than the albums which immediately preceded and followed it, Balaklava (1968) and The Use of Ashes (1970). Rapp stated that it was the first Pearls Before Swine album which reflected drug use in the writing of the songs.
The album sleeve showed a 15th century painting of Christ by Giovanni Bellini. The picture was removed from the version of the album issued in Germany because it showed Christ's nipple exposed.
The album was reissued on CD in 2003, originally as part of a box set, Jewels Were The Stars, which comprised the group's four completed Reprise albums.
