Michael Penn...his back catalogue on mix up on my iPod.
I bought his debut March back in mid-1990 and have had it on hand ever since. It's just one of those albums you put on and leave on.
He always seemed destined to be something bigger but after his first single No Myth, never repeated the popularity. That said, he's just a gem of a muso. Every album is a treat and littered with bittersweet musings on the human condition.
It's funny to think he's the third Penn brother, after Sean and Chris (RIP) but he's really one of those 'undiscovered' treasures.
These days, he's eschewed the standard album creation process to concentrate on film/TV soundtrack work (Boogie Nights was one of his) and has recently contributed a few new songs to the Girls soundtracks and scored Masters of Sex.
I highly recommend March and his third LP from 1997, Resigned.
