Between her tart, melancholy voice and fondness for tuneful, semi-psychedelic guitar pop, you'd think Sam Phillips would be at least a minor sensation by now. So far, though, the public at large has remained distressingly indifferent to her charms. But if there's any justice in this world, "Martinis and Bikinis" will change all that. As with her previous work, the album is packed to bursting with exquisite instrumental textures and delicious mind-melting melodies, from the luscious, Lennonesque "Love and Kisses" to the pungent, guitar- charged punch of "Same Changes." And the best tracks, like "Baby I Can't Please You," are so irresistibly tuneful that it takes only a single play in the morning to leave you humming all day.
