Trouble with the release of the album led to Holden going bankrupt, losing all his equipment and his departure from music for over two decades. Population II was eventually released multiple times in bootleg forms over the years, with no official re-release until a limited issue in LP in 2005 and finally a remastered CD in 2008. The album has become a much-sought-after collectors' item over the years. After more than two decades he returned to his guitar, and began creating music again, reportedly at the continual urging of a loyal fan. He recorded Guitar God in 1994 and released Guitar God 2001 in 2001, followed in 2008 with the release of Raptor. In 2008 Richie Unterberger said "He's a good candidate for selection as the great unknown 1960s rock guitar hero. No other American guitarist was as skilled at creating the kind of sustain-heavy, snaky guitar lines pioneered by Jeff Beck in the Yardbirds. His recordings with the Fender IV, The Sons of Adam, Ugly Things, The Other Half, and Blue Cheer, as well as his solo recordings, don't only contain some feverishly innovative playing, they also chart the overall rainbow of changes undergone by California 1960s rock guitar as a whole, from surf to pseudo-Merseybeat to psychedelia, hard rock and heavy metal." In 2010, Holden began working with Randy Pratt (Cactus) and drummer Bobby Rondinelli (Black Sabbath, Rainbow, Blue Oyster Cult) on Population III, released by Ridingeasy Records on July 1, 2022. Pratt and Holden both composed the songs on Population III.<ref> "Population III." Ridingeasy Records, "nofollow">https://randyholden.bandcamp.com/</a>. Liner notes. July 1, 2022.
