Most of the time an artist does an in-store that consists of just signing or in most cases a short 20 minute set.
JD McPherson played Amoeba Records in Los Angles on June 1st.
If you do not know his music…run!

He played a full 55 minute set, probably more time then he is getting on Robert Plant’s tour (Cheers for the continued good taste Mr. Plant!)
Large crowd great set, and it felt like it was 1957 and Wallichs Music City was down the street WOO and a Hoo!
