Writer John Lingan posted this to Twitter - the 1973 summer concert lineup at Maryland's Merriweather-Post Pavilion. Look at that lineup! Pink Floyd! (Same year they released Dark Side!) The Kinks! Beach Boys! Stevie Wonder! Miles Davis! Jerry Lee Lewis! I think my favorite listing is back-to-back shows by Quicksilver w/ ELO and James Gang w/King Crimson.
