>> five years after his death prince continues to influence popular culture. later this year his estate will release an album called welcome to america, filled with songs about racial equality and social justice and stashed much of his recorded material in a vault. even though he launched a welcome to america tour, none of the songs were heard, until now. >> dearly beloved. >> reporter: here he is on that 2010 tour. the riddle wrapped in a mystery wrapped in gold lamet. "let's go crazy" was one of five number one hits. when prince died he was selling more albums than any other living musician.

to unravel the prince paradox, we started here, paisley park in minnesota, a suburb of minneapolis, his hometown. from the outside, there is nothing paisley about it. enter, and the place is a trippy, dreamscape, oc accented in purple, not green. a pair of doves overhead is still white. >> there you go, enjoy your tour. >> this is where the party would happen. >> now a museum, it wasn't just where prince worked, he lived above the shop so he could make music any time the inspiration struck. the prince estate invited us inside. we sat at prince's sound board with his long time keyboardist and musical director, morris hayes. he gave us a preview of that missing album, welcome to

america. ♪ ♪>> reporter: deleeriusly versatile, prince wrote, sang and played most instruments. he asked hayes to add production values. >> here is the record. i want you to overproduce it. >> is there another song from the album? >> sure. this is called check the record. ♪ ♪ let's check the record see what it says see your girlfriend in my bed ♪ >> reporter: typical prince, the album resists genres. ♪ ♪ >> did he ever say why he didn't put it out there? >> no. i remember asking him about it.

he said well, we will have to revisit that down the line. he was just on to the next project. you think that is what it was? >> i never saw anybody that had that much work inside of them. just this unending stream of music.teays n exaggerating. for four decades prince worked to a furious beat, releasing an album roughly every year. yet most of the music that prince created and recorded was never released. by one estimate 8,000 songs, hundreds of albums never left paisley park. >> music ain't milk. it don't expire. there was nothing strange about getting that call at 2:00 a.m. and he got inspired and wants to record something. what are you doing. i am asleep. it is 2:30 in the morning. he is like you want to sing. do you feel like singing.

yeah, prince i feel like singing. how soon can you get here. >> reporter: how often would you record something that was great that wasn't released? >> that was all the time. >> i asked him about what is going to happen to this music. somebody will do something with it. he knew it would see the light of day. >> reporter: prince one floor below the studios in what he called the vault. the sheriff's office got inside during a 2016 investigation into prince's death at paisley park and eventually ruled an accidental overdose of painkillers. age 57 prince died with no spouse, children and crucialally no will. his sister and five half siblings have been named heirs but are locked in a legal sfut over the estate. the bank overseeing the estate called in troy carter, one time

lady gaga manager to sort out the music collection and unlock the value. >> the prince vault, this legendary thing. my first visit to paisley the first place that i wanted to go is to see the vault. it is literally a vault, a room full of shelves with tapes. you have recorded music. a video archive. you have a written archive, you know, just looking at the penmanship, the drawings that he would do, you know, little red corvette there, is a picture of a little red corvette in the lyrics. i literally have chills on my arm right now. i remember the first time seeing the lyrics. >> do you have favorite songs that are down there? ♪ ♪ same page but a different book so much more common if we only

look ♪ >> reporter: on the rare occasions that he mentione it at all, prince downplayed the music he didn't release. here he is in 2014. >> is there a huge vault of mterial? >> i do not go back in time to listen to it. i worked on it. brought it as far as i could right then. a lot of it i did not even finish. >> reporter: we learned for all its, prince stayed out of the vaults for the most mundane of reasons. >> they told me he hadn't been in the vault for years, i thought there would be a story of how he left behind the old materials to focus on new endeavors but no he forgot the password to the vault. he started to put stuff in this vault and it turned into more and more rooms. >> reporter: iron mountain is a secure repository in california.

a team kept pace with prince, putting out roughly an album a year. a mix of re-releases and newly mined gems. >> sometimes when we think that we have the plan, we will come across something that blows our mind. >> reporter: in 1983, a year before the release of "purple rain" he recorded this rehearsal session, just him at the piano working out new arrangements. >> there is a piece on that project, him crafting purple rain. to hear the seeds of the idea and to see how the song was sort of formed and then to finally get to, you know, that

zone? >> quite literally, yes. >> reporter: william is a boycott and loved camping until covid came along. he thought what better way to challenge himself than to put up a tent and sleep in it longer than any backyard camper ever has. a year and a day. >> stopping him from doing anything is a fool's errand. >> reporter: his parents let him give up his warm, cozy bed in exchange for howling coyotes and bitter cold, blizzards, sweltering heat and worse. i want to give you a chance to defend your parenting. a hurricane went through. >> yes. >> you let him stay outside? >> we put the tent under the deck to protect from the wind. >> reporter: how many trees did you lose? >> six. >> reporter: and how many sons? >> none we know of. >> reporter: the bulk of the

storm had passed by nightfall and william is a hurricane in his own right. >> if i start something, i have to finish it. if i don't finish it i would be so upset. >> reporter: parents often push their kids but it moves them no closer to success, because the prod has to come from within. william was determined to sleep outside a full year, and this week he made it. his next goal, to end world hunger. does not know how yet, but you can bet that tonight he is sleeping on it. steve hartman, on the road in wilton, connecticut. >> that's the cbs overnight news for this thursday. for some of you the news continues. for others, check back later for cbs this morning and follow us online any timeat cbsnews.com.
