Most attractively packaged, these four CDs comprising the new survey of British songwriting are issued by NMC recordings to mark the 20th anniversary of its indispensable activities; poetically evocative photographs of the initial letters, drawn from pubs, floral clocks, blue heritage plaques, transport directions, shops, warehouses, fruit barrows, etc., spell out the salient words, and promise a rich and sparky diversity of contents amply fulfilled when one knuckles down to listen.
