Virgin were onto a winner (artistically speaking) when they chose to issue a Rare Bird best of drawn only from the first two albums. Every track was excellent on them so its inevitable the compilation is excellent. Shame its not longer. 5 tracks from '1st' & 4 from 'Mind Flies By'. Brilliant organ & guitar work. Probably closer to the darker, heavier end of pysch than to prog. Good stuff to get spaced to. If you can't afford to buy '1st' & 'Mind Flies By', then buy this. Actually you should scrape together the cash & buy all three.
