Query: Five is Not Enough Stars

This album is entirely without peer. "Bolero" is hands-down one of the two or three best pieces of electronic music ever released. Heldon is the most underrated pioneer band of all time; it's a travesty that tinky-tinky noodlers like Kraftwerk are universally known while Heldon languishes in obscurity. "Interface" and "Stand By," the last two releases under the name Heldon (Richard Pinhas' solo releases are only non-Heldon in name) are stunningly, boldly, unapologetically and aggressively *electronic music*; not ordinary music with obtrusively analog waveforms, but genuine explorations of a new and powerful medium. "Stand By" sounds no more dated than Bach. While other synth acts were doing gee-whiz material and even ELP would use sounds that sounded merely weird, Heldon was composing within the new potentials.Play this! Listen! If you're not moved and stunned you should stick to mainstream music, which this emphatically is not.
