• With an overflowing crush of CD releases in the next two months, new artists and new albums will have to fight for the back-to-school dollar against a host of exciting, expanded CD re- issues. Honored as the best rock album of the 1980s by the editors of Rolling Stone, The Clash's London Calling from 1979 was a life-changing experience for many, in a magical time when these godfathers of punk walked away from the mangled production of 1978's Give 'Em Enough Rope and said: Why not a double album then, and a triple-album set next (in 1980)? Due next month on Epic's Legacy label, the bonus material is to die for, with demos from the era recently discovered by guitarist Mick Jones, rare photos, and new writings reflecting on this 25th-anniversary edition.
