I've always been a big fan of " TUSK ", it has so many different levels to it that make it an amazing album to me. I've also been a big fan of Lindsey's work outside of the band. His one solo release " Out Of The Cradle " is a hidden masterpiece of sound and creativity.
By "one solo release", I assume you mean that one in particular? Because it's hardly his only solo release...his first two ("Law And Order" and "Go Insane"), in particular, should be of interest to any Beach Boys fan, but there have been plenty more since then.
