Above is a short (2:25) instrumental featuring Geddy Lee on a fretless bass, “Malignant Narcissim”. He got the guitar delivered as they were mixing an album and was noodling around with it when it first arrived.
The sound guy hit “record” and when Geddy was done played it back and said “How about another song for the album?” They reworked it a bit, Neil was still there with a small warm-up kit still so he added his part. Alex had already gone home, so he listened to their stuff and mixed in his guitar on his home studio.
Malignant Narcissim is the name of the song - not the guitar!
