Blue-Sky Research is Taproot's third major label album which was released on August 15, 2005 internationally and a day later in the United States. Smashing Pumpkins frontman Billy Corgan co-wrote three songs on the album. Jonah Matranga from Far and Onelinedrawing and Deftones guitarist Stephen Carpenter make guest appearances. The band wrote over 80 songs for the effort. "Calling" was released as the first single and was a moderate hit, while the second single, "Birthday", followed quietly. It is Taproot's last album with Atlantic Records, as both parties have decided to part ways. It has a different, softer, more alternative melody from the first two albums. The album has sold over 140,000 copies in the U.S., despite little label support.
"Calling" was released in late 2005. It was used by the WWE as the theme song for their Unforgiven pay-per-view event in 2005.
Received radio airplay on June 27, 2005.
Music video premiered on MTV.com.
Another song titled "Who's to Say" was recorded during the Blue-Sky Research sessions but has yet to be officially released on CD because of record politics. Stephen Richards was hoping for it to be a single, but was disappointed that it did not make the final cut. The song was, however, available for download on the band's official MySpace page for a limited time.
"Facepeeler" was supposed to be the band's third single, but because of record politics and poor album sales, it did not make it as a single. However, the band did have a contest for the fans to create a music video.
