John Frusciante's Trickfinger project was recorded 10 years ago with no intention of ever being released, made purely for discovery and the learning experience. All the music was recorded live onto a CD burner, through a cheap mixer. John would sit on a chair in his living room surrounded by 5 to 15 machines, programming and jamming until the track was ready to be recorded. There were no overdubs; it was recorded live. Acid Test unearthed these recordings and John agreed to have them released. Trickfinger II is the second part of recordings made during the winter of 2007. Frusciante explains, "In my opinion, making music with no intention of releasing it is the best thing a musician can do for his own development in this day and age. The Trickfinger LP (2015) was made in that mindset, and it was the beginning of a new musical life for me. When I hear it, it sounds like I am opening up doorways to new worlds, and I never have had that feeling listening to music I made for the purpose of releasing it and selling it."
