These days, there is no shortage of instrumental progressive metal acts. The subcategory is currently saturated with superb artists creating intricate, imaginative tracks without the need for vocalists. Modern listeners are well-acquainted with the technical prowess of bands like Liquid Tension Experiment, Animals as Leaders, Scale the Summit, Intervals, and Plini.
However, the landscape was vastly different in the 1990s. While the genre had begun to take shape a few years prior, the decade offered only a handful of truly outstanding instrumental releases that remain essential listening decades later. The albums we have selected—some of which come from artists not typically pigeonholed into the prog metal box—represent the finest early examples of how inventive, challenging, and alluring the style could be.
In curating this list, we have restricted ourselves to one album per band. While some of these records may feature subtle vocal elements like spoken passages or background textures, they maintain zero focus on traditional singing. For all intents and purposes, these are instrumental masterpieces.
Whether you are a seasoned expert or a novice looking to explore the roots of the style, these five albums are mandatory listening.
5. Michael Angelo Batio, No Boundaries (1995)
We told you to expect the unexpected! Although Michael Angelo Batio (known for his work with Manowar and Nitro) is often celebrated as a quintessential glam metal shredder, he possesses a deep, long-standing affinity for progressive and neoclassical metal. This is perhaps most evident in his solo output, and his 1994 debut LP remains his most compelling effort.
The prelude, “Intro: This CD Is Dedicated to You,” features Batio delivering his signature high-speed shredding, almost as if to reassure longtime fans before taking them into uncharted territory. While he retains his technical flair on tracks like “Rain Forest” and “The Finish Line,” much of the album explores complex rhythmic shifts and symphonic tonal shifts in “Science Fiction” and “No Boundaries.” The record culminates in the multifaceted “Outsideinside,” which stands as a testament to his progressive potential.
While No Boundaries may not be as overtly influenced by ’70s prog rock giants as, for instance, Dream Theater’s Images and Words, it is a remarkably inventive and thoroughly enjoyable record that bridges the gap between technical shred and progressive composition.
