In reply to Pursued by a bear:
Anything by Ian Brown solo or with the Stone Roses. He's appallingly bad at singing (especially live). Hasn't stopped me buying his music and seeing him live though...
John Leckie managing to engineer his vocals for the Stone Roses album is a miracle. Memorable NME reviews of live gigs include quotes like, "like a drunk man shouting into a bucket".
Still a brilliant front man though!
