Also genuine question but what books are there that are considered trustworthy?
Hi Julia. Well, seeing that no one else has answered yet, the books I myself trust implicitly are Peter Ames Carlin's
Catch a Wave, Jim Murphy's
Becoming the Beach Boys, 1961–1963, Ian Rusten and Jon Stebbins'
The Beach Boys in Concert and AGD’s
Complete Guide. Add two websites -- AGD's
Bellagio 10452 and Ian's
BeachBoysGigs, both unmissable -- and Jon's books on David and Dennis and you're definitely among writers you can trust.
The forthcoming definitive sessionography project will fall into this category too. Like those named above, none of its authors is given to speculation or flights of fancy.
