Tom Petty & the Heartbreakers spent much of 1986 on the road as Bob Dylan's backing band. Dylan's presence proved to be a huge influence on the Heartbreakers, turning them away from the well-intentioned but slick pretensions of Southern Accents and toward a loose, charmingly ramshackle roots-rock that hearkened back to their roots yet exhibited the professional eclecticism they developed during the mid-'80s. All of this was on full display on Let Me Up (I've Had Enough), their simplest and best album since Hard Promises. Not to say that Let Me Up is a perfect album — far from it, actually. Filled with loose ends, song fragments and unvarnished productions, it's a defiantly messy album, and it's all the better for it, especially arriving on the heels of the well-groomed Accents. Apart from the (slightly dated) rant "Jammin' Me'" (co-written by Dylan, but you can't tell), there aren't any standouts on the record, but there's no filler either — it's just simply a good collection of ballads ("Runaway Trains"), country-rockers ("The Damage You've Done"), pop/rock ("All Mixed Up," "Think About Me") and hard rockers ("Let Me Up [I've Had Enough]"). While that might not be enough to qualify Let Me Up as one of Petty & the Heartbreakers' masterpieces, it is enough to qualify it as the most underrated record in their catalog.
