Base Jam is a band formed on January 15, 1994. Their personnel lineup originally consisted of Adon Saptowo (Vocals), Sigit Wardana (Vocals), Adnil Faisal (Guitar), Ardi "Aris" Isnandar (Guitar), Bambang "BS" Sutanto (Drums), Intan "Anya" Putri Werdiniadi (Keyboards) and Ardhini "Sita" Citrasari (Bass). It all started with the Seventeen event, the brothers Aris (guitar) and Sita (bass) and their cousins, Enya (guitar), and Sigit (vocals), were offered to appear at the Seventeen event held by the Jasa Marga office, where at that time they were employees of the company, in July 1993. In mid 1994, Enya and Arif resigned. To fill this void, Adnil (Arif's younger brother) was chosen as the guitar player. With this formation, Base Jam made another achievement. They were chosen as the Band's General Champion in the grand final event of a similar music competition. Since then, Base Jam began to frequently fill events at schools, colleges, cafes, and radio shows. Like other bands, these seven young men tried to compose their own songs. Sita's father, who happened to know Harry Sabar, took them to "study" him. With the help of these senior musicians, the band successfully created four songs and recorded them in demo form. In 1995, PT Musica Studio's was interested in the demo song material and proposed a cooperation contract for four albums. Their debut album, Dreaming was successfully released in mid-1996. The name Base Jam was immediately counted as the most successful newcomer band that year. In its development, apparently the band's personnel were moved to be more serious about playing music. In an effort to build a more solid band, they also invited Anya to join as a keyboard player. Following later, BS (drums), Adon (vocals) and Arif (backing vocals). With this formation, they made their first appearance at the Ministry of Public Works event in November 1993. At that time they still carried the name JM's KIDS (Jasa Marga Children). The name Base Jam itself was officially used on January 15, 1994. The word Base is taken from the initials of the eight personnel's names, while 'Jam' can mean Jasa Marga or Jam Session. The name Base Jam seems to be a blessing, because that same year they won the best talent title in an event organized by Prambors radio.
Base Jam first signed a contract with PT. Musica Studios, and released the first album, Dreaming (1996) and the second album 2 (1997) and the third Ti3a (1998). Then in 1999, Base Jam experienced a personnel crisis after releasing the album Ti3a, Adnil Farsal (guitar) and Intan "Anya" Putri Werdiniadi (Keyboard) decided to resign from Base Jam. Before Adnil and Anya resigned, Base Jam had achieved several encouraging achievements. They were selected as the 'Most Wanted Band Anteve, MTV Video Music Award 1999. The song Not a Pujangga was chosen as the best song at the Anugerah Musik Indonesia (1999) and won the category of Favorite Video Clip for the Indonesian Music Video version (February 1999). It was followed by BS who decided to take a hiatus from music for a while due to drum practice, but Base Jam did not die of creativity, after the resignation of its 2 personnel, Base Jam released their 4th album called Sinergi Base Jam Emp4t (2000), in their twentieth album. 4 Base Jam collaborated with other singers and musicians, one of whom was Iwa K. The vacant position on the Base Jam guitar that had been left by Adnil was then filled by Christopher "Coki" Bollemeyer. This guy who graduated from the Guitar Institute of Technology, Hollywood was appointed a permanent member of Base Jam after a year Coki became an additional player. Coki began to join Base Jam on the 5th album Dari Hati (2001) replacing Adnil Farsal (guitar), but only one album later also left and decided to join Netral in 2002. Coki's position was then filled with the return of the former Adnil Farsal guitarist. After the 5th album was released one year later 2001-2002 Base Jam released The Best of Base Jam 1994-2002 which contained the best collections of Base Jam songs and there were 2 (two) new songs and as their singles namely Withmu Withoutmu and hits single Cloudless Rain. One year later, Base Jam released their sixth album entitled Dua Sisi (2003) which was the last album before Sigit Wardana chose to leave and join the Nufa Band and pursue a solo career. Bambang Sutanto alias BS chose to leave because he has worked in the graphic design and culinary fields. However, there were also those who joined, namely Oni Fathoni (Guitar) and Wally (Drums - former Jun Fan Gung Foo) who joined to fill the vacant positions left by Coki (Guitar) and BS (Drums) since 2002. Base Jam was vacuum for several years, Adon Saptowo was busy with a solo career for his spiritual album, Ardhi "Aris" Isnandar was busy with college, and each personnel with their personal affairs, so in 2010 they Base Jam began to reunite and bounce back from suspended animation, they call themselves The New Base Jam where the personnel are Adon Saptowo (Vocal), Alvin Kurniawan (AFI Finalist) (Vocal), Ardhini "Sita" Citrasari (Bass), Ardi "Aris" Isnandar (Guitar), Oni Fathoni (guitar), and Echa Soemantri (drums). In 2010 "New Base Jam" released a single entitled I'm different, Sayang, Believe and a song called Doamu Ibu as a compilation of the soundtrack for the Indonesian feature film Negeri 5 Menara. In 2015, Base Jam celebrated 21 years of Base Jam's creation. And this is marked by the emergence of their new album, Base Jam Reunion 21 Years. On this album they reunited with their two old members, Sigit Wardana and Adnil Farsal. Bambang Sutanto or BS as the former drummer for Base Jam this time only acts as a designer for the cover of this album.
