Way back when, I bought these 2 books on the same day-
Jazz Riffs For Bass - Rick Laird
Rock Riffs For Bass - Tom Wolk
I am assuming your Laird book is different that what I have.
Anyway, knew Laird from the MO...at the time, I did not know Tom Wolk.
Of the two books, I really got nothing from the Jazz Riffs book. IIRC, scales, modes all pretty much in 1/8th note exercises. Not the stuff I could practice...I liked playing songs.
Wolk's Rock Riffs, though...kept my interest. It was a quick study of various Rock, Jazz, & R&B/Soul players. The music was a sampling of stuff in their style.
Just a walk down memory's lane because, honestly, there were not too many electric bass books available at the time.
