With three albums to his credit – “Intravenous Delusions”,  “The Psychology of Booze & Guilt” and the upcoming “Magnetic Roots” – and hundreds of live performances, Professor Gall (aka Drew Norman) has carved a niche into the dark corner of Portland’s musical scene.  It’s a tincture of junkyard folk and nefarious jazz, coalescing the sounds of late-night Broadway and Bourbon Street.
