Task: Question Answering
Input (English): Passage: Smiley Smile became the first in a three-part series of lo-fi Beach Boys albums (preceding Wild Honey and Friends) and the first in a seven-year string of under-performing Beach Boys albums (ending with the 1974 compilation Endless Summer). The Smile era is generally viewed as the ending of the Beach Boys' most artistically creative period, and the point after which Brian began relinquishing his hold as the group's creative leader. After Smiley Smile, Carl took Brian's place as the most musically dominant member, and Brian would not be credited as producer for another Beach Boys album until 1976's 15 Big Ones. Journalist Brian Chidester designed the nominal "Bedroom Tapes" label as a catch-all term for the work produced by Wilson in between his "full retreat as leader of the Beach Boys [in mid 1968] ... following a brief stint in a mental institution" and his admittance under Eugene Landy's 24-hour therapy in late 1975. By 1969, Wilson was increasingly known for his reclusiveness, and could be found managing a health food store in West Hollywood called the Radiant Radish.Much of the group's recordings from 1967 to 1970 continued the pattern of sparse instrumentation, a more relaxed ensemble, and a seeming inattention to production quality. Harrison opined that this experimental songwriting and production phase lasted until Sunflower (1970), after which their albums "contain a mixture of middle-of-the-road music entirely consonant with pop style during the early 1970s with a few oddities that proved that the desire to push beyond conventional boundaries was not dead".After Smile was cancelled, some of its tracks continued to trickle out in later releases, often as filler songs to offset Brian's unwillingness to contribute. "Cool, Cool Water", an outtake from Smiley Smile and Wild Honey sessions, was partially rerecorded and issued as the closing track for Sunflower. When The Smile Sessions box set was released in 2011, co-producer Mark Linett acknowledged that "there's things that some people think – should Smiley Smile sessions be there – [with tracks such as] 'Can't Wait Too Long', we get into a very fuzzy area". In 2017, additional session highlights from the album were released on the rarities compilation 1967 – Sunshine Tomorrow. The compilation was followed several months later with two more digital-exclusive releases: 1967 – Sunshine Tomorrow 2: The Studio Sessions and 1967 – Live Sunshine. 
Question: What is the first name of the person who is known for his reclusiveness?
