This week on All Songs Considered, we grapple with the alchemy of creation — the myriad ways a musician gets from blank page and empty studio to a full sound and lyrics that ring true. The seven songs on the show (one is a collaboration between a drummer and a pair of remixers) follow on that theme: Each posits a means of making magic out of circumstance. For one group, the key was stripping away ambition and returning to a single voice. For others, sparse hometowns, the ghosts of previous albums and mysterious romantic entanglements provided the spark needed to reach forward into the dark and, as sung by Jeen on "Everywhere I Go," burn it bright.
