Lindsey Buckingham’s first solo album builds on the dream-pop of 1979’s Tusk, but here the author is given the full control he was always pulling for in Fleetwood Mac. The sound design of Law and Order is sunlit and airy — one imagines these songs flowing from a room of glass walls and air conditioning. Buckingham’s taste might be cloudless and breezy, but these songs are still rooted in the fundamental styles of doo-wop and rockabilly. “Mary Lee Jones,” “That’s How We Do It in L.A.,” and “Love from Here, Love from There” reveal Buckingham’s lifelong fascination with Buddy Holly, while “I’ll Tell You Now,” “It Was I” and “September Song” form a suite of sock-hop slow dances. Law and Order is all about atmosphere, but at the same time, Buckingham’s songwriting chops have never been stronger, and his pop sensibility has never been sweeter. The album is anchored by a reading of the country standard “A Satisfied Mind,” while the twinkling single “Trouble” is a vision of unrivaled immaculacy and loveliness.
