With regard to LANA LANE and her inclusion into PROGARCHIVES, I for one would certainly add her, for two simple reasons, i) her husband (Whilst having two entries - Rocket Scientists and Erik Norlander) appears and produces all her material (not surprisingly), but so too does members of the two aforementioned groups appear in the instrumental line ups, ii) whilst she does fall squarely into the Symphonic Rock, she undoubtably has prog overtones, both with her husbands involvement but also with her nod to some of progs worthies.
The output by this spousal team is prolific and since they work consistently on each others material this provides further reasons for her inclusion, I'm sure that others would agree that without the one you would not necessarily get the other...
