Alycia Baumgardner Vs. Christina Linardatou

Liberation arrives in 2018, six years after Lotus, by far the longest stretch of time between Christina Aguilera albums. During that hiatus Aguilera wasn't exactly in hibernation but she wasn't prominent, taking a couple of seasons off from the televised singing competition The Voice to raise a child and spending as much time onscreen as she did on-stage when she re-emerged in the middle of the 2010s. Aguilera may have been omnipresent in showbiz but she was largely absent from the pop charts. Save a handful of duets – "Moves Like Jagger," which appeared in 2011 in the first flush of The Voice's success; "Feel This Moment," a 2013 Pitbull hit; "Say Something," a 2013 Great Big World single featuring Christina on vocals – Aguilera hadn't reached the American Top Ten since 2008's "Keeps Gettin' Better," fanbait added to her hits collection of the same name.

The latest album from Christina Pluhar and her instrumental ensemble L’Arpeggiata sheds new light on the chamber cantatas of 17th century Italian composer, Luigi Rossi. He wrote more than 300 of these works and Christina Pluhar’s new double album includes an impressive number of 21 world premiere recordings, which are the fruit of Christina Pluhar’s research among music manuscripts held in the Bibliothèque Nationale de France and the Vatican Library.
