We're going way back this week, to 1964 and The Stones' 2nd US release 5 x 5.
"2120 South Michigan Avenue" is a short instrumental jam, inspired by Chicago blues and R&B, the title being the Chicago address of the business offices and recording studio for Chess Records, home to Muddy Waters, Bo Diddley, Little Walter, Willie Dixon and so many others. The Stones recorded the song there at the Chess studios during their first US tour.
For me, the best part is Brian Jones' harmonica playing, simply fantastic. That's Ian Stewart on keyboards, and Keith Richards playing the tremolo guitar riff.
Every band has its influences and the Stones wore theirs right there on their sleeves.
