If ∆ were to fully embrace their pictogram then they would be tapping in to a current zeitgeist for lexically inoperable band and album names. For instance, rapper M.I.A’s latest record /\/\/\Y/\ is functionally unsearchable. The artist intends this as a statement of withdrawal from the exploitation of Web content economies. M.I.A, along with other performers such as Gr†ll Gr†ll and Λ, is of a generation of musicians that have grown up with the Internet and recognise that it is often a less than benign force.
Symbols against labels
Of course, such rebel taxonomies predate Google by some margin. 80s band Freur (a nascent Underworld) were initially represented by a vaguely Celtic squiggle that their record label later insisted must have a pronounceable counterpart. In the 90s Prince famously change his recording name to the love symbol as a means of “emancipation from the chains” that bound him to Warner Bros. The label reportedly had to mass mail floppy disks containing a custom font in order for The Artist Formerly Known as Prince to be properly referred to in print media.
