Recorded over several years. These were new recordings collected together and self released on CDR in 2000. Perhaps a more acoustic feel to things, with (not sure why) a tropicalia feel to some of the tracks. The majority of tracks are longer than those on 'No.1'. The 4-track tape machine (Yamaha MT-120) was used in conjunction with a demo of Wave Lab Lite (for some editing and further manipulations).

Here is a review by John Kennedy in the Dominion newspaper, Wellington New Zealand .

"4tRECk Album No.4 (4tRECk). Sometimes-uplifting sounds appear from far less exalted sources, like the humble home studio of Londoner Sam Callow, a.k.a. 4Treck. These instrumental pieces are played entirely by Callow on guitars, wind instruments, drums and various keyboards.

What you get is some very infectious tunes and many doses of mostly successful experimentation with the recording process. Folk Metal Eight has a have-to-smile melody cycle, re-iterated in multiple layers and a backdrop of sped-up voices artificially wavering but strangely moving.

There are echoes of Brian Wilson style genius and the sort of eclecticism that was almost an endangered species - check the titles: Kamchatka, Eastern Promise and Bossa Not Over. Behind the playful attitude is a considerable, self-contained talent. The forecasted graduation to 8-track recording for “Volume 5” promises much."

And another by Simon Berkovitch in Comes With A Smile (No. 9):

"As the name suggests, the work of 4tRECk is a series of musical journeys documented on one of the simplest forms of home recording equipment: the beloved 4-track tape machine. In the eyes of 4tRECk (or indeed his alter ego Sam Callow, composer arranger and 'label boss'), the utilisation of basic equipment need not be seen as a limitation to ones musical progress. Quite the opposite in fact: Sam relishes the challenge of finding new ways of making the most primitive technology produce interesting results. This fourth CD-R release sometimes finds our intrepid hero in the arena of world music, but mercifully without any pretensions of authenticity. Elements of various musical cultures are absorbed and reworked through the 4tRECk four track, with a surprisingly hi-fi sound. The bulk of the album is a semi-acoustic affair, with various picked guitar styles pleasingly prominent. The opening 'Folk Metal Eight' offers whimsical English folk rock guitar accompanied by a series of recorders and bowed string instruments, very much in the vein of the quirkier music of the celebrated film score of 'The Wicker Man'. This folky style is reworked in a jaunty instrumental piece witha blues/Cajun feel ('Acoustique') and again in the raga frenzy of 'Eastern Promise', with additional psychedelic effects of treated cymbal washes and fizzing electronics. It seems that 4tRECk has great affinity with the grand tradition of the eccentric outsider artist, as the accordion led 'Recordian pt 2' has its roots in the mantras of Ivor Cutler. Elsewhere, though, things just get plain weird. The very one-man band nature of this project means that 4tRECk is keeping time with himself whilst 'playing' a series of instruments via the four track. Anybody familiar with The Legendary Stardust Cowboy`s 'Paralysed' will understand how frightening this notion can be. Eccentric time signatures and instrumentation fight for centre stage all over tracks such as 'Harmonique' and 'Kamchatka'. The brutal guitar/drums battle of 'Imp Heavy' attempts to demonstrate what The White Stripes might sound like if their primary influence was the Wyatt-less Soft Machine, instead, instead of grungy swamp blues. These progressive recordings are not for the faint hearted, especially as 4tRECk elects to conclude #4 with a disgusting cut up 35 second rearrangement of Survivor's 'Eye Of The Tiger', with discordant riffs reassembled at random. This shouldn`t come as too much of a surprise from a man who has covered the theme from 80s helicopter drama 'Airwolf' on 4tRECk #3. The overall mood of 4tRECk #4 is split between the off kilter acoustic pieces and deranged experimentation, but in both instances 4tRECk`s maverick DIY spirit remains untamed."

And a French review by Stephane from Autres Directions:
"Les trouvailles du prodige Sam Callow aka 4tRECk viennent de donner vie à un quatrième morceau de bravoure. Alors que nous nous remettions à peine de ce no.1 (voir ci-dessous) qu'il nous avait fait parvenir afin de nous présenter sa musique (et que son inspiration débordante avait permis la réalisation de no.2 & no.3), 4tRECk publie no.4, un disque qu'il décrit comme son plus acoustique.

La légèreté bucolique, la finesse des arrangements et la simplicité de la mélodie font de Folk Metal Eight, le titre qui nous berce en ouverture de l'album, un petit moment de détente au charme désarmant. Mais la musique de Sam Callow ne peut pas se tenir droite plus de 6 minutes au compteur, et après une évolution vers un mathcore acoustique, elle termine sa course effrénée par un hymne guitaristique rock. Certains titres tendent d'ailleurs vers un certain post-rock (The Sorts), acoustique qui plus est (sur Bossa Not Over, Kamchatka), voire Gastr Del Sol ou Jim O'Rourke (sur Recordian Pt.2, Acoustique) - soient des références très éloignées de no.1. L'humeur est également ici moins festive, plus mélancolique. Le son est généralement très particulier : les méthodes d'enregistrement du garnement sont comme les pochettes de ses auto-productions, frappés du sceau diy (4tRECk s'enregistre seul, chez lui, sur quatre pistes et parfois sur MD) ; et ce son "cheap" rend sa musique encore plus chaleureuse, présente, colorée. Ainsi, ce lointain neveu de Daniel Johnston compose des mélodies touchantes avec les vieux instruments qui traînent au fond de sa jolie cave (guitares, violons, percussions, harmonium, piano), comme ce No No No No qui pourraît être un Black Heart Procession enjoué. Enfin, le disque se clôt par trois dernières chansons plus courtes, qui renvoient davantage à son no.1 car plus barrées, bruyantes, avec cette drôle de relecture -méconnaissable- de Eye Of The Tiger...

No.4 est un disque régulièrement surprenant, émerveillant. Et 4tRECk de devenir, pour ces quelques instants, l'artiste le plus émouvant qui soit. "
