Query: Elvis Costello's "My Aim Is True" is a real gem

Elvis Costello is one of the most influential and inspired musicians of the last quarter century, and his debut album "My Aim Is True" is his quintessential masterpiece. From the rip-roaring "Welcome To the Working Week", to the blues inspired "Blame It On Cain", and his gentle, yet brutally honest love ballad "Alison", "My Aim Is True" beautifully exhibits the full range of his talents. He pours his emotion into each note as though the guitar were an extension of his body, manipulated as easily as flexing a muscle. His emotions are not masked as is evidenced in "Wave A White Flag" his ode to spousal abuse, but rather they complete the songs, allowing for a touch of tenderness to dilute even the cruelest anthems. While his influence is certainly not as far reaching as that of the Beatles, Dylan, or Hendrix, it is no less poignant.
