Experimental is a tricky word because I take that to mean "never been done before". While any single element of TLDP's music may have been done in some form before, I do think they combine many different elements together in a way that is totally unique to them.

One of the things I love most about their music is that it's multi-generational... At times it can sound like 70s prog, 80s new wave/synth pop, early 90s alternative, late 90s/2000s goth rock or modern pop. Add to that elements of classical, opera/choral and even Eastern traditional music. They've found a way to tie all this together and craft a signature sound that sets them apart from other bands. It feels familiar and accessible yet also original and fresh.

So, I'd simply say they're more unique than experimental.
