Query: a great, catchy album

U2's first album is one of their best. Every cut exudes energy especially tracks like "I Will Follow" and "Electric Co." Bono's voice is raw and the Edge's guitar soars with his trademark galloping riffs. I have always liked U2 but it's their early stuff that I really enjoy. Buy either "Boy" or "War" and you won't go wrong. Avoid "Rattle and Hum" and everthing after 1991's "Achtung Baby".
