Albert Hammond Jr., guitarist for The Strokes, identifies five guitarists that have influenced his writing style: George Harrison for his unique sound and inspiring philosophical musings, Mike Campbell for knowing when to show off or serve the song, Elliot Easton for giving The Cars an edge with his playing, Lou Reed for his melodic side and underrated album "Loaded", and John Lennon's album "Plastic Ono Band" for its immediate emotional impact and depth. Hammond Jr. will perform at the Sinclair in Cambridge on Sunday.
