One into amazing Bush LP issue (7)
I believe the answer is:
publish
'issue' is the definition.
(I know that issue can be written as publish)
'one into amazing bush lp' is the wordplay.
'one' becomes 'i' (Roman numeral).
'into' is an insertion indicator.
'amazing' indicates anagramming the letters.
'bush'+'lp'='bushlp'
'bushlp' is an anagram of 'publsh'.
'i' placed inside 'publsh' is 'PUBLISH'.
(Other definitions for publish that I've seen before include "Issue, make known" , "Damned if I do!" , "Report" , "Get into print" , "Make generally known" .)
