Yeah, Sipiagin definitely seems like an arranger to be reckoned with. I'd love to hear him do some more arrangements for some other projects, maybe even other singers. But I don't know of too many singers who could hang with his charts. He makes some significant contributions to Routes as well, as both player and arranger.
He and Monday make a helluva team. Between her songs (never mind the production & arrangements, they're great songs, period) and his arrangements (never missed when they're not there, but when they are, they stand out immediately, in the best way), this is a team that is making some significant music.
But ultimately, it's Monday's show. The woman has skills, if you know what I mean, and she's got a spirit. She's indeed "reminiscent" of a lot ot things, but I really dig how she ultimately adds her own twists and upgrades and ends up sounding not at all "retro". Whatever she starts with, she ends up turning it into her own.
Case in point - 1994's Maiden Japan, from her club/acid-jazz/whateveryou callit days.
Probably more electronic/techno/etc than most here would feel comfortable with, but it's still an incredibly musical album. This ain't no "diva" being propped up by artifice and cast as a idealized "object", this is a woman with something serious to say saying it in her own way and on her own terms. Ain't no bullshit going on here.
America, wake the hell up!
