Gabriel's - right - I'd forgotten about
Brian Berryman - haven't heard his stuff, mind, but he certainly did do at least one CD.
@ Rob - Bart Kuijken is stunning on Baroque flute, but I've never come across a recording or seen mention of him playing even 4-key Classical, let alone 8-key - if you know of any such in his output, please share details!.... I'm sure he's capable, but I don't know of any such output.
FWIW, most of the Period Instrument classical pros reckon to carry around a kit of 4 flutes, from what I've read - a French style early Baroque at A=392, a German High Baroque/Rococco style at c A=415, a 4-key Classical at c A=430 (for Mozart etc.) and a late C18th or early C19th style 8-key (and most of 'em are proficient Bohm players too....). That said, and I've followed the Period Instrument/Historically Informed Performance movement for nearly 30 years, I know of very few recordings specifically using 8-key flutes (for example, I have John Eliot Gardiner's period instrument version of Verdi's
Requiem of 1874 - in which the flautists play wooden French Louis Lot Bohm flutes made in the 1860s), and certainly not in solo virtuoso repertory.
The ones I mentioned that Stephen Preston did back in the 1970s and 80s include pieces on 8-key flutes - in duet with Lisa Beznosiuk on the second album, including a superb rendition of Kohler's
Valse des Fleurs. The solo album has him playing Nicholson's variations on Home Sweet Home on a 7-key Nicholson Improved. Preston also did an album of Weber's
Flute Trio and Sonatas played on a Koch 10 keyed flute.

I'm pretty sure I've done Amazon links for those in the past on C&F.
I think you might find some recordings of the Mozart concertos on 4-key Classical flutes - though I'm not sure off-hand by whom - perhaps John Solum or Janet See? There are certainly quite a few recordings on 1-key flutes. But there's a dearth of C19th stuff.
Here's a scan of the album (vinyl LP!) cover of Preston's Music For Two Flutes album showing the actual flutes they used for the pieces by Haydn, Mozart, Drouet and Kohler:-
Early C19th London-made ivory flutes - a 10-key by Hill, late Monzani & Co. (1831-2) and an 8-key by Drouet c1825.
So much for the Classical side - I mentioned Malo Carvou from Brittany - check
this out - he uses the full chromatic capability of the flute for sure, and in ways/to an extent I don't think Barou or Veillon do, geniuses though they be. There's more of Malo there on YT if you hunt about. I think that although his material is not what you asked for, Radcliffe, his playing style/technique/ability may be!
Again, not playing Romantic repertory (though I'm sure she can) there's our own Adrianne Greenbaum
playing klezmer on Germanic simple system - a Meyer here, I think. (Radcliffe, you should come to her
Manchester day-course! Sign up and help get the numbers to make sure it happens!)
