How long did he generally take? I know next to nothing about him - other than Cliffs of Dover.
Not that long really, by Axl Rose standards.... but it was a good 4 or 5 years between albums , in the days before it became the norm to take that long.
I'm pretty sure Guitar Player interviewed him more than once between the
Ah Via Musicom and
Venus Isle albums, talking about things he was working on which never even made the latter album (which also changed title more than once). Which would have been fine if
Venus Isle was worth the wait, but I found most of it extremely bland.
I always compare Eric Johnson with Robben Ford, who (to me at least) is a bit like Johnson in the sense that he's a slick, sophisticated blues player with some jazz and rock influences. Ford releases loads of albums and doesn't seem at all "precious" about spending years in the studio perfecting everything - but the results are still great. Johnson (IMO) should have the same attitude.
