and there's a lot i don't listen to *waits for vk veterans to come with more recommendations* so there will likely be no shortage of cool tunes to check soon mUAHAHAHA wait on it

emmny's recs are on point, but it's also worth mentioning SID's first album "Renai", which honestly is jazz-rock at its best and pretty much started this whole jazzy thing in modern VK. Other bands like SCISSOR, Shichisanshiki and Kazoku also had some really good jazz-inspired stuff.

i guess some of Merry's stuff might apply? although i feel like it's more kayokyoku-inspired than jazz, but still
