I saw this on PE. I don't know what to think about this since it is only 2nd album without Barre, and this took me by complete surprise. Well here is the announcement:
TAAB2 - Whatever Happened To Gerald Bostock? - is a full length Progressive Rock "concept" album worthy of its predecessor. Boy to man and beyond, it looks at what might have befallen the child poet Gerald Bostock in later life. Or, perhaps, any of us. To be released in two formats: the simple jewel case CD with 8-page booklet and the Special Edition with CD, audio-visual DVD and 16-page booklet. The DVD contains 5.1 surround mixes, 24-bit stereo mix, videos covering the making of the album, interviews with the musicians and the lyric reading where ian Anderson reads the lyrics in various settings. Also on the DVD are the pages of StCleve.com, the online update of the St Cleve Chronicle, fabled newspaper of the original album, and the multilingual lyric translations in Italian, German, Spanish, Czech, Polish and Russian.
This is released as Jethro Tull's Ian Anderson. I think the official date of release of April 2nd was picked otherwise everyone would think of it as an April Fool's joke
