Shana Halligan and Kiran Shahani’s debut album as trip-hop duo Bitter:Sweet last year was elegant and cosmopolitan, spawning a slew of remixes (but doesn’t everything?). This album collects some of the more notable ones, from the excellent but unsurprising bossa and lounge stylings of Nicola Conte and Thievery Corporation, to the funky Fort Knox Five remix of “Salty Air,” to the horn-heavy, spacey Yes King remix of “The Mating Game” (the title track of the 2006 album). Skeewiff’s rock guitar-laced “Dirty Laundry” and the acoustic guitar-backed “Moody” from Marsmobile further push the boundaries. Halligan’s sultry vocals and Shahani’s polished production are quality source material, and the versatility here keeps it as distinct and enjoyable as the original.
