LP: 1972 Numero Uno
While originals of Formula 3 and Il Volo albums are relatively inexpensive to source (though not cheap either), Radius is extremely rare. Most likely the album didn't sell squat in its day, and I don't think it was ever imported to the States (i.e. can't recall seeing one with a Peters Intl sticker). I lucked out in my acquisition - truly a quirk of ebay one Sunday night in 2004. Someone had 5 Italian prog albums listed as a Buy-it-Now for $10. Right place, right time. 2 of the albums were common US presses, and one wasn't very rare at all. This was the pick of the litter of course. There are multiple CD presses, all basic and domestic to Italy, but I've never plunked down for one. Not sure I need to honestly. Oddly it's never been issued in Japan like most albums from Italy.
What the album cover is supposed to project, I couldn't hazard a guess. Fun with tomatoes? Inside a red painted refrigerator? Guessing the budget had run out by the time the art department was ready.
