*Yggdra Union Perfect Audio Collection PLUS VGCD-0028
The second Riviera soundtrack I posted is basically the same as the first Riviera soundtrack I posted, except the second one has the original game music for the Wonderswan and Gameboy Advance versions as well. Yggdra Union was done by the same composers as Riviera, so they have a similar vibe. The Union soundtrack comes with both the original and arranged version.
I can’t remember for sure, but I think both Riviera and Yggdra Union have quite a few rock-based tracks in them, as well as some tracks that have a techno feel to them. Either way, they’re both decent arrangements.
You could also try the Guilty Gear series as it’s all rock-based, though it’s not as "complex" as the stuff you’re used to hearing.
