The group is made of of the two members Terada Minami (25) and Komuro Sayaka (23).
Minami's hips don't lie...
alom（アロム）is a word with a double meaning. One, A Lot Of Music. Two, a dutch word meaning anywhere. Avex lists their style as a Technopop Unit (in the Summer Zombie description on CD Japan at least), which immediately conjures the thoughts of YMO, and YMO they are not, but whatever it is, I like it. So they are not idols, just hot ladies.
As one might expect the two girls (currently singing Anime songs) were singing anime songs by themselves, before teaming up. Both are singer songwriters. At least before Alom.
