On the surface, a 1928 jazz record by Louis Armstrong and a 1978 hard rock
track by Eddie Van Halen seem to inhabit completely different universes. But
musically and historically, "West End Blues" and "Eruption" are
practically sibling recordings.
They are arguably the two most influential instrumental
performances in 20th-century American music, and they share a striking amount
of DNA. Here is what connects them:
1. The Revolutionary, Unaccompanied Opening (The Cadenza)
Both tracks shattered the existing rules of their genres by
starting with a jaw-dropping, unaccompanied solo that served as a showcase of
pure virtuosity.
- "West
End Blues": Armstrong begins with an incredibly complex,
12-second unaccompanied trumpet cadenza. It features rhythmic freedom,
rapid-fire arpeggios, and a cascading descent that was light-years ahead
of anything anyone had ever heard on a brass instrument in 1928.
- "Eruption": While
technically a standalone track (though it famously segues into "You
Really Got Me"), "Eruption" is essentially a 102-second
unaccompanied guitar cadenza. It begins with an explosive, unaccompanied
flourish that instantly signals a new era of guitar playing.
Both intros function exactly like a classical cadenza-an
ornamental, highly improvisational passage played by a soloist to show off
their technical mastery while the rest of the band stands aside.
2. They Shifted the Focus to the "Soloist"
Before these recordings, both jazz and rock relied heavily
on ensemble dynamics and structured, rhythmic accompaniment. These two
performances permanently shifted the spotlight.
- From
Ensemble to Soloist: Armstrong’s work on "West End
Blues" single-handedly transformed jazz from a collective, New
Orleans-style ensemble improvisation into an art form centered on the
brilliant, individual soloist.
- The
Dawn of the "Guitar Hero": "Eruption" did the
same for rock. It didn't just popularize two-handed tapping; it
established the guitar solo as an independent, sovereign piece of art,
setting off the entire 1980s "shredder" movement.
3. Classical DNA Sneaking into Pop Culture
Both players used classical structures and techniques to
revolutionize "street" music (blues and rock).
- Armstrong utilized
operatic drama, classical phrasing, and a perfect, dramatic arc in his
opening run, elevating the blues to a high-art form.
- Van
Halen drew directly on classical violin and keyboard etudes
(specifically borrowing a chord progression from Kreutzer's violin etudes)
to create the lightning-fast, fluid arpeggios that anchor the tapping
section of "Eruption."
4. The "Year Zero" Effect
There is a distinct "before and after" line in
music history drawn by both of these tracks.
"The opening cadenza of 'West End Blues' is the most
influential instrumental introduction in jazz history. After it was released,
every trumpet player and indeed every jazz musician had to change how they
played."
The exact same can be said of "Eruption." After
1978, every rock guitarist had to learn how to tap, rewrite their solos, and
completely rethink what the electric guitar was capable of expressing.
In short, both Armstrong and Van Halen took their respective
instruments, blew up the existing boundaries of what was physically thought
possible to play on them, and laid down a blueprint that defined the next fifty
years of music.
