premise: Neilson Hubbard is an American singer-songwriter, musician and producer. His first band was called This Living Hand formed with Clay Jones. They signed to Adam Duritz's label, E Pluribus Unum. After the band split up, Hubbard went on to record three solo albums, "The Slide Project", "Why Men Fail" and "Sing Into Me". He also collaborated with Matthew Ryan to form the band Strays Don't Sleep.
hypothesis: "The Slide Project" was released under the "E Pluribus Unum" label.
reason: It may or may not have been released under his previous label. He might have signed a new contract. It may have been difficult because it seems logical to assume that the label remained the same due to lack of evidence otherwise.
