Here's an excerpt by Charls Donovan, about her latest recognition of one of the top 20 reissues of 2019 
In 1973, Clive Davis was prepping one of his charges for the big time. Pamela Polland, a glamorous singer/songwriter/pianist with a soul-melting, expressive voice, was already notable, having written for Linda Ronstadt and the Byrds. Her first solo album (Pamela Polland, 1971) had sold steadily, but not enough to make the charts. Off she went to London, working with Elton John's producer, Gus Dudgeon, and David Bowie's engineer, Ken Scott, at Trident Studios in Soho. The album, Gas Station, for short, was given a gatefold design and a catalogue number and readied for the presses. Then, disaster.
Clive Davis was fired from Columbia. Projects associated with him were postponed or canceled. Polland's album never came out. Music that could, indeed should, have transformed her from cult favorite to rising star stayed in the vaults over 40 years. Finally, it emerged via reissue powerhouse, BGO, in spring 2019, A grave injustice has, at last, been partially righted. - Charles Donovan
