In case people here may not have clear knowledge of Gamelan music, here is the overview of Gamelan music:
Styles can be roughly categorized into three major styles, each has its own style very vaguely described:
(1) Javanese: Big ass gamelan orchestra comprising 40+ players, usually related to old Javanese royal courts, such as Yogyakarta and Surakarta (Solo). The overall texture is much much thicker than the other two styles, with tempo and atmosphere generally more sophisticated and serene.
(2) Balinese: Modern day most popular form of Balinese Gamelan is the Gamelan Gong Kebyar, it can be very very fast and very very loud, and usually comprises much lesser players, the fundamental characteristic is the drastic contrasts in tempo/dyanmics/mood.
(3) Sundanese: Generally rather lyrical in musical expression and voice leading, the orchestra is significantly smaller than Javanese Gamelan, and slightly smaller than a typical Gamelan Gong Kebyar band.
Very brief overview of the Gamelan musical structure:
(1) The core voice and musical strata: Basically there is a core voice (for example in Javanese term the "Balungan"), all other instruments play an elaboration based on this core voice, creating different musical layers in different registers in a heterophony fashion.
(2) The drum being the leader: usually the drummer plays the kendang (or sometimes other drums, and sometimes in pairs i.e. two players being leaders), its role is to signal important musical events, and often times the drum players serve as the rehearsal leader or sometimes played by the composer themselves (in the Gong Kebyar case).
(3) The interwoven melody (Kotekan in Balinese Gamelan): often times the melody is being played by a pair of players, each playing the instrument that was tuned in a slightly different tuning (typically 8hz), the most standard Kotekan is that, (in the sense of western notation) the first player plays all the odd number notes, and second player the even number notes. Kotekan in Balinese music comes in varying styles and forms which I shall not delve too deep into. (for those interested the Michael Tenzer book is a must-read).
(4) Cyclic in form structure: Traditionally the music will be in the form of simple repetitive cycles, the beginning/end of each cycle marked by the biggest gong (the gong ageng). Different sections of classical repertoire will have different cycles, the cycles serving different ceremonial purposes and in different moods.
(5) The strong beat is always on the last beat, in comparison with the standard western 4/4 being [Strong, weak, Second-strong, weak], Gamelan accent structure often is [weak, second-strong, weak strong].
I've always loved gamelan music itself, and the gamelan-hybrid music that has become pretty popular in the western world music scene.
==================================================
I'll give a few examples of the pieces that I myself really loved, here are the hybrid/Gamelan-influenced pieces:
Lou Harrison: Lou wrote in varying degrees of hybridizations, but gamelan has been one of his major inspirations.
(1) Main Bersama-sama (in a quasi-Sundanese style featuring Western solo instrument)
(2) Concerto for Violin and Cello with Javanese Gamelan
(3) La Koro Sutro (Esperanto lovers would like this piece)
Claude Vivier: The Canadian composer was the reason why I delved into gamelan in the first place, his gamelan influences also come in varying forms.
(4) Cinq Chansons for Percussion
(5) Pulau Dewata
Akira Nishimura
(6) Ketiak inspired by the Balinese vocal music Kecak
(7) Legong inspired by a Balinese dance Legong, in Bali dances are almost always accompanied by Gamelan music,
Other composers and groups in Gamelan hybrid music are listed below for further references:
Evan Ziporyn, Michael Tenzer, Daniel Goode, Gamelan Son of Lion, Godowsky, Jack Body, The album "Beat!" by Gamelan Padhang Moncar (one of my all-time favourite album), Gamelan Pacifica, John Cage "Haikai for Gamelan", Gareth Farr, Gamelan Galak Tika, Espen Aalberg.

Also some Gamelan Gong Kebyar music for your reference, all in Balinese Gong Kebyar style, as I'm most familiar with this style.
Johannes Brahms.
