Nigel Senada, may or may not have been born in 1907. Similarly, he may have died in 1993 at the age of 86. Allegedly, he was one of the Residents' earliest collaborators, having arrived in San Mateo, California, with Philip Lithman. He was a Bavarian composer and music theorist and the man who formulated the "Theory of Obscurity" and the "Theory of Phonetic Organization".

In 1937, N. Senada premiered his masterpiece, "Pollex Christi", which means either Big Toe- or Big Thumb of Christ. This work mainly consisted of stolen pieces from other composers work, namely Beethoven's "5th" and Carl Orff's "Carmina Burana", among others. He also left large holes in the work so that the performers could insert music of their choosing, thus "becoming composers themselves". Senada justified his work with "house" analogies claiming that he didn't make the "bricks" but "cemented them together"; he wasn't the "architect", just the "builder".

Senada allegedly worked with the Residents on their pre-Santa Dog work, and then disappeared. He reappeared during the recording of Eskimo (which he allegedly inspired in the first place).

The Residents performed "Pollex Christi" as a tribute to Senada on, what would have been, his 90th birthday. The holes in the piece were filled with various pieces such as the television theme from Star Trek.

The recording was distributed in two editions of 400 before being deleted.
