Speaking on a hard rock/ metal angle;
When I started going to gigs back on the nwobhm guitar and drum solos were the norm. Especially big / outdoor gigs . I remember angelwich frontman doing a guitar solo at their gigs and he was dreadful ( probably the only person at ghe gigs who thought so). Ted nugent on the other hand, played entertaining guitar without excessive noodling . The power is in the song.
Go forward to Metallica'live sh@t binge. & purge, all the band did a solo of some sort . Seek and destroy lasted ages so everyone gets a rest because of a 3 hour set. They could've done us all a favour and cut the set to 90 mins and saved us from the solos.
With joe satrini , if stu Hamm is with him , then it's probably the best time to see a bass solo .
Sheehan as mentioned also.
When I saw scorpions on the crazy world tour, there was a solo there too. Unexpected and uninteresting . It reminded me of slap ( a trend that everyone is doing a bass solo for the sake of it).
At dream theatre , it's expected but it's mainly inaudible and cr@p.
Rammstein are my fave live band , probably ever and just put on a fantastic live show .
Maiden don't bother either..
Kiss and Crüe do it , just for tackiness .
I would expect to see bass solos at Jazz gigs , and would welcome it
