Are the band members the same? Then it is an alias \ change of name.
Are the band members different? Then maybe it is a different group.
A test I often do is - is this on the band website now as part of the discography? So they play these tracks now or have they “moved on” from this early project?
If it was an early project name before they became serious, you can look to Radiohead who were initially called On A Friday
I think this project doesn’t exist anymore.
So I guess “Boosta:Iconoclash” would be the “project/band” name, and members would be DJ Boosta and the other two guys (TBH, I’ve always known that this release was from Boosta, who is also member of “Subsonica”).
There is no “band site” as such, so I can’t check if it’s in their discography or not.
