Lindsay Buckingham/Christine McVie, released in June, is an album no one expected from people who haven’t collaborated since 1998. Most of Fleetwood Mac’s current lineup can be heard on the album, which was originally planned to be the 18th studio album for the band. But the titular team brings an edge to the iconic rhythm of Fleetwood Mac, which has been active for almost half a century. McVie returned to the stage in 2013 after 15 years away. Buckingham, on the other hand, has steadily released new music during his equally on-again, off-again tenure with the band. Together, however, they haven’t skipped a beat, trading off lead vocal duties from song to song, reminiscent of the 1982 album Mirage. The album has a “Hotel California” vibe, utilizing flowing instrumentation that would have sounded right as rain on early ’80s radio under the alternating lyrics of Buckingham and McVie. In Irving on Tuesday, McVie and Buckingham will bring the soul of Fleetwood Mac while supplying the heart themselves.
