Do not ask yourself whether it is psychedelic jelly but whether it is NOT psychedelic jelly. This may then lead you to imagine the complete ABSENCE of psychedelic jelly. Or perhaps the complete absence of anything BUT psychedelic jelly (this one sounds like more fun). As is often said about UFOs, “absence of evidence is not evidence of absence” but, then again, there is Goethe Mandelbrot's quote that “all that is outside, also is inside”.
Making much more sense is The Electric Guitars at the Gasometer with an amazing lineup of fellow star-gazing gutter-dwellers: loveable rascals Loose Tooth, loveable dreamers Jukai Forest & just-plain-loveable Gareth Ed Lindsay.
