Around this time, Valle began writing music for TV programs and telenovelas (soap operas), which over the next few years would become one of the main outlets for his work, along with advertising jingles. "Marcos Valle" (1970) (often referred to as "The Bed Album" due to its cover shot of Valle in bed) contained his most adventurous as well as his most rock-influenced and psychedelic music up to that point. Backed by Milton Nascimento's band Som Imaginario, Valle explored a more eccentric approach, with a number of futuristic tracks and an extended instrumental suite not unlike the work of U.S. composer and producer David Axelrod. "Garra" (1971) was a career highpoint that summed up his music and still stands as one of the finest pop albums of the era, Brazilian or otherwise. Its effervescent pop, jazz, soul, bossa, and film soundtrack stylings were matched by lyrics that attempted to reconcile Valle's hippie leanings with his status as a wealthy young musician who was also a successful businessman because of his successful novela soundtracks and corporate advertising accounts. Telenovelas he provided some or all of the music for during this period included "O Cafona", "Uma Rosa com Amor", "Minha Doce Namorada", "Pigmalião 70", "Os Ossos do Barão", and, most prominently, "Selva de Pedra". He also wrote the score for the film "O Fabuloso Fittipaldi" (1973).
