Airing tonight is the 100th episode of the CBS hit drama The Mentalist. Blake Neely (Arrow, The Pacific) has been written the music for the entire series, beginning with the pilot episode in 2008. For the landmark episode – a flashback to the main character Patrick Jane’s (played by Simon Baker) first few days in the California Bureau of Investigation – Neely’s score employs a poetic 100 different instruments, and treats central character themes like debut statements. Neely’s music is mainly electronic, with live instruments layered in. Neely’s palette for the series has been defined both by musical voices he chooses not to include (brass, clarinet), as well as the use of several unorthodox instruments. The 100th episode of The Mentalist airs tonight on CBS.
