Z23 and Penga
Listened to Butch's Z23 on Bandcamp to get an idea of his type of music.
I downloaded some MRI sounds and time stretched 100% one to get a 2 1/2 minute base track. Cut it in half and rejoined so the ends met in the middle using audacity. Asked Butch to add a cheesy piano loop through it. Next got him to add some found sounds.
Finished by adding some samples from Just a Minute radio show, Nickolas Parsons at the start and Paul Merton at the end.
Cover art evolved from a picture I had taken of a frost damaged flowerpot "artistically rearranged", originally I added Butch's picture like a stamp on a card but asked Butch if he could turn it into an Obi.
Butch added the title and artist names.
So my gear was a PC and Audacity and Paint
Butch Canfield (Z23):
I found the cheesy piano loop in GarageBand. Edited the hypnotism samples I found online in Audacity and mixed the track in GarageBand. I added the text to the art supplied by Pen in Photoshop as well as the Obi strip of my artwork.
