Live at River Plate is AC/DC’s first live album in 20 years.

“We don’t speak Spanish very good, but we do speak rock and roll. Let’s go!”

And so opens metal giant AC/DC’s first live album in 20 years, Live at River Plate, which features 19 songs from the band’s live tour in Buenos Aires, Argentina. Set to be released on a three-disc red vinyl package and a two-CD package that includes a booklet from the tour, the album pulls music from the DVD of the same name, which came out last year.

Live at River Plate is a rollicking good time for both fans and the band alike — something made evident on most of the tracks. And while AC/DC may not make the most complex or compelling music, they are, much to our delight, still rocking after all these years.

The album is composed of numerous old favorites such as “Hells Bells,” “Thunderstruck” and “Back in Black,” though it does include a few newer tracks off of the band’s most recent album, Black Ice, as well.

However, the album’s shining moments come in the form of AC/DC’s most well-known and well-liked tracks of the past. On these, Angus Young’s voice is as raspy and voracious as ever — he leads the rest of the band in rocking renditions of these classics.

“Back in Black” is especially good, as Young goes on an epic tangent of vocal harmonization with his brother Malcolm at the end of the song.

Live at River Plate does have its pitfalls. During the show, AC/DC interlaced their old and new songs, and it’s clear which ones the audience — and the band — prefers.

The newer songs, such as “Black Ice” and “Big Jack,” are just boring in comparison to AC/DC’s previous work. They lack the energy from the band members that was present on tunes like “T.N.T.” and “Thunderstruck,” and it shows.

Part of the problem may simply be the audience is not as engaged as they would be on the more well-known tracks — understandable, but also a bit disappointing nonetheless.

Fortunately, the band saves itself by finishing off the album with impressive renditions of “Highway to Hell” and “For Those About to Rock (We Salute You).” The energy and edge of these tracks leave audience members remembering that AC/DC is always about to rock. We salute them.
