At the age of seventeen, Adams sent a few demo recordings to A&M Records and was signed to them, by the age of 18, for one dollar. He has written and released fourteen albums since then. Some of the first demos written in 1978 have surfaced over the years, most notably "I'm Ready" (recorded for both the album Cuts Like a Knife and later his release for MTV Unplugged) and "Remember", which went on his first album. Both songs were covered by other artists before his first album was even released. This time was also the start of a long songwriting partnership between Adams and co-writer Jim Vallance, which led to the first solo album, Bryan Adams, released in 1980. His second album, You Want It You Got It (1981), contained the FM radio hit "Lonely Nights", but it wasn't until his third album, Cuts Like a Knife, that he broke through with four hits in 1983, most notably with the title track. He quickly followed up that album with Reckless at the end of 1984, which produced six Top 40 songs, including "Heaven" and "Summer of '69". Reckless has since been certified five times platinum in the US.
