The group are re-releasing material from their years with Mercury Records in chronological order each month throughout 2015; they started in January with 1975's "Fly By Night" and will wrap it up in December with 1989's "A Show Of Hands."

All albums are being reissued on high-quality vinyl with a download card for a Digital Audio version and high resolution Digital Audio releases, while three titles will also be released on Blu-ray Pure Audio.
